INTRODUCTION

Extra High Voltage (EHV) power cable is a major back bone of the electric system. The reliability and safety of the electric power transmission system essentially depend upon the quality of the cable.

Traditionally Paper/ Oil Insulation systems have been used in High voltage transmission cables. However, since the advent of synthetic polymer, polyethylene (PE) and cross-linked polyethylene (XLPE) have been used as an insulation material. In most countries the use of polyethylene have been limited to the cross-linked version (XLPE) due to major advantage XLPE has over PE in that it enables the cables to be operated at a higher temperature and results in higher current carrying capacity.

Cross-linked polyethylene is also considered to be the material of choice due to its ease of processing and handling as compared to paper/oil. In addition, the low dielectric losses of cross-linked polyethylene which become increasingly important with increase in voltage as well as high intrinsic electrical strength makes it the favored material for the range of extra-high-voltage applications.

These cables can be designed to meet requirements of international standards such as IEC, ICEA, UL, DIN, VDE, AS/NZS, TIS, IS as well as other standards specified by customers.

INTRODUCTION

HT Cables or High Tension Cables are cable defined as per IS 7098 Part II having voltage grade from 3.3kv to 33kv. Cables of similar voltage range are also defined as MV Cables or Meduim Voltage Cables as per IEC-60502 part 2, BS-6622 & BS-7835

INTRODUCTION

Low voltage cables are most widely used among all cables. Low voltage power cables are used in electric power distribution and control cables carry signals from electrical devices, switchgears, etc to control room. LT Cables or Low Tension XLPE Cables are defined as per IS 7098 Part I having voltage grade up to 1.1kv. Cables of similar voltage range are also defined as LV Cables or Low Voltage PVC Cables as per IEC-60502 part 1 and BS-5467

XLPE insulated cables are generally manufactured up to 1000 sqmm(Single Core) and 630sqmm(Multi Core) conforming to IS, IEC & BS standards.

The XLPE insulated cables were introduced worldwide in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature.

The advantages of XLPE Insulated cables in comparison to PVC insulated cables are as under:

Technical Advantage

INTRODUCTION

The steady growth in automation of production processes in industry, especially distributed process control across large user sites like oil refining and petrochemical plants, the steel industry, power stations etc. necessitates the reliable transmission of electrical signals, process data and control information.

Today, in a continuous process plants like refinery, fertilizer, cement, steel etc. various parameters like temperature, pressure flow, level etc. are converted  into electrical signals which are fed to control room. In control room these signals are analyzed, compared and suitable commands are sent to the field to take corrective action.  The control room has become the brain of the instrumentation cables are the arteries.

Instrumentation cable are mainly defined in Indian Standard IS 1554/7098 Part 1, British Standard BS5308 Part 1 & Part 2 and European standard BS EN 50288-7, amongst others. We can also work with customers to develop cables designed and manufactured to meet their applications' specific requirements for industries including oil, gas & petrochemical, automation and process control, and marine & offshore.

Instrumentation cables have very diverse applications and are designed for use in communication and instrumentation applications. Cables made to specific rigid requirements and standards are used in process controls, transmission of critical signals, control and automation systems, and monitor networks as well as in intrinsically safe systems in hazardous areas like oil, gas and petrochemical plant, power plants, etc.

Some of the major national standards according to which we manufacture our instrumentation cables include:

INTRODUCTION

Flame proof motors are equipment which can perform safely in the following conditions:

Hazardous Area

An installation where inflammable products are continually handled, processed or stored requires special care to ensure the maintenance of property and the personnel safety.

Based on their characteristics, electric equipment can become ignition sources causing sparks, when opening or closing contacts or due to overheating of any component, caused intentionally or originated by fault currents.

Explosive Atmosphere

An atmosphere is considered explosive when the proportion of gas, vapour, dust, fibres, or flyings is such that after sparking caused by short-circuit or overheating of one component causes an ignition and explosion. Three elements are required for an explosion to occur:

Fuel + oxygen + ignition = explosion

INTRODUCTION

TEFC squirrel cage induction motors specifically designed for DOL operated Crane duty / intermittent duty application. The motors are designed to take care of the high electrical and mechanical stresses arising due to frequent starts - stops associated with intermittent duty application. The motors are compact providing high output for a given frame size and have low inertia. These salient features make them most suitable for EOT Cranes.

FEATURES

Brake motors are ideal for applications that require immediate, accurate and safe stops, position control and energy saving. The brake motor is suitable for many different applications, such as load elevators, hoists, shears, machining equipment, looms, packaging machines, conveyors, washing and bottling machines, bending machines, among others.

The brake motors are simple & rugged & so easy for maintenance. No separate DC supply is required as the rectifier is provided which gives the required DC voltage for energisation of the brake. The rectifier is mounted inside the main terminal box so no separate terminal box required.

INTRODUCTION

Designed basically for heavy duty use with driven machine imposing overloads and severe mechanical shocks and vibrations. These motors are equally suitable for smooth constant loads since the motors are also designed with high efficiency and power factor. Because of optimum utilisation of materials, with improved ventilation techniques the motors are 10 – 15% lighter in weight and yet more rugged because of their inherent special construction.

Because of high Pull Out Torque and inherent thermal margin kept for high slip operation (with suitable external resistance) these motors are ideally suited for rerolling mills and cane cutter/cane crusher/cane leveller/cane fiborizer applications pertaining to sugar industries. Because of high efficiency and power factor these motors are also suitable for pump/fan compressor applications.

INTRODUCTION

Torque Electric motors are induction motors designed for applications which require occasional or prolonged stall, or controlled applications nearly stalled. The basic difference between a torque motor & a standard induction motor is in the shape of the speed torque curve and thermal capacity to withstand locked rotor currents. Torque motors are rated at locked rotor torque where standard motors are rated in horsepower.

A standard squirrel cage motor tries to maintain the speed as it is loaded while a Torque motor will drop in speed as it is loaded. The desired speed can also be achieved by varying supply voltage.

CONSTRUCTION

Torque motors are normally induction motors of toroidal construction. Their main differences from other similar motors are their wide diameters, to allow for high levels of torque, and their thermal performance, to allow their continuous operation while drawing high current in a stalled state.

Torque motors suitable for 415V±10%, 50Hz±5%, combined ±10%, 3 phase supply, foot mounted (B3 construction), ambient temperature 50°C, Class 'F' insulation, IP55 protection, continuous rated (S1 duty) with bare shaft & key as per IS: 325 / IEC: 60034-1.

They are designed for continuous duty corresponding to Duty Type S1 of IEC 34-1 and BS4999, part 101 section 3, with a temperature rise by resistance not exceeding 80K in a maximum ambient temperature of 40°C.

These motors are rugged motors can be custom designed to each customer’s specific application. Because of their design versatility and high operating efficiencies, our motors are the logical choice for a multitude of industries including oil and gas, petro-chemical, pulp and paper, electric utility, water and waste water, marine, steel, mining and air separation. Typical applications include agitators, blowers, boring mills, pumps, conveyors, crushers, fans, and many more.
 

INTRODUCTION

Smoke spill motors are designed to withstand required operation at elevated temperature. Smoke Extraction Motors comply mechanically and electrically with the requirements laid down European Standard – EN12101-3 (Specification for powered smoke and heat exhaust ventilators).

Motors in conformity with this standard are able to provide daily ventilation, as well as for driving smoke extraction fans in a fire/emergency condition. In fire emergency condition, they must be effective in creating a smoke-free area near the floor allowing possible evacuation and rescue of people and animals, as well as ensuring property protection and allowing that fires could be fought in their initial stages. These systems also help eliminating hot gases produced by combustion in the first stages of the fire.

INTRODUCTION

Generation of electrical power in low voltage level is very much cost effective. Theoretically, this low voltage level power can be transmitted to the receiving end. This low voltage power if transmitted results in greater line current which indeed cause more line losses. But if the voltage level of a power is increased, the current of the power is reduced which causes reduction in ohmic or I2R losses in the system, reduction in cross sectional area of the conductor i.e. reduction in capital cost of the system and it also improves the voltage regulation of the system.

Because of these, low level power must be stepped up for efficient electrical power transmission. This is done by step up transformer at the sending side of the power system network. As this high voltage power may not be distributed to the customers directly, this must be stepped down to the desired level at the receiving end with the help of step down transformer. Thus electrical power transformer thus plays a vital role in power transmission.

• Finish : Polished Aluminum
• Sizes from 2.5 Sqmm to 300 Sqmm

INTRODUCTION

Whenever aluminium cable is terminated on copper bus bar or copper contact and aluminium lugs are used then contact between terminal lug and copper bus bar being of dissimilar metals leads to galvanic action. Also if copper lug is used then contact between aluminium cable and barrel of copper terminal lug the galvanic action takes place. Thus in order to prevent and avoid galvanic action it is always advisable to use copper-aluminium Bi-Metal lugs.

CONSTRUCTION

In Bi-Metal lugs barrel of the lug is of aluminium and the head or palm of the lug is of copper.
This ensures contact between aluminium cable to terminal lug is of aluminium and contact between terminal lug to copper contact is of copper.
Thus contact between dissimilar metal is avoided and contact between similar metal is established.
Thus Bi-Metallic or galvanic action is completely eliminated and hence technically sound and durable joint is achieved.
Electrolytic copper head / palm is friction welded to electrolytic aluminium barrel.
If aluminium cable is to be joined with copper cable then Bi-Metal in line connectors are to be used.

INTRODUCTION

Latest Compacted sector shaped multi-stranded conductors/cables are thinner than comparable lineages. Hence conventional tubular cable lugs and connectors usually have too much play- a considerable safety risk. This has led to design of sector shaped lugs due to huge demand globally of sector shaped cables. The following difficulties occur with sector shaped conductors when round connecting material is applied to sector shaped conductors/cables.

Often both cables lugs and conductors, are deformed or the conductors break

INTRODUCTION

Single Compression Gland as per IS13942 or as per IS-1394 the compression is effected only at one place (i.e.) at the cable armour only. There is scope for moisture and corrosive vapour to enter the gland and thus into the cable. Generally single compression glands are used for light armored cables

INTRODUCTION

Double-Compression Gland as per IS13947 or as per BS-6121 the compression happens both at the cable armour as well as at the inner sheath. This is sort of two sealing. Hence, chances of moisture or vapour entry are minimised. Thus these glands are also known as Weather-proof cable glands or Flame-proof cable glands. Double compression glands provide extra support to the heavy armored cables entering or exiting the panel
