In the last twenty years, we have supplied well over 2,50,000 relays and devices to various users in the country and all of them are giving satisfactory service. We have formal approvals from all the Electricity Boards like KPTCL and distribution companies, APTRANSCO and distribution companies of AP, TNEB,KSEB, MSETCL & DISCOMs, GETCO & DISCOMs, GRIDCO, RRVPNL & DISCOMs, UPPTCL & DISCOMs, HPSEB, J&K Power Development Department, WBSEB,CESC, etc for the use of our relays up to 220kV systems. Our relays have been purchased by almost all the leading switchgear manufacturers.'

Supplier: Japanese quality switchgear components, breakers, magnetic contactors, switches, pilot lights, pushbuttons, panel instrumentations, power management meter, protection relays, transformers, inverters, ups.

Switch gears. Thermopore Packing.

SIVACON 8PV is the most advantage type of Siemens. The Max current is 6300A for MCC.

Use for power supply. Packing of 10 piece.

ASN3-12 air-insulated metal-clad enclosed switchgear is a new mv switchgear on the basis of introducing advanced techniques from foreign, abstracting our experiences in manufacturing the center located switchgear and assembling the world top class numeral controlled equipments. It is major used in 3.6~12kv 3-phase ac50/60hz power system to receive and distribute electrical power. Also it is used to control, protect and monitor the circuit. 1.The surfaces of conductors in the primary circuit are all disposed with vulcanization process. Thus the insulation lay have the characteristic of good attachment, high temperature endurance and even surface comparing with the static electricity process. 2.The frame is made of aluminum-clad zinc board together with rivet nut and high strength bolt. 3. Can be fitted with vn3 series center located high voltage ac vacuum circuit breaker. 4. With the function of manual urgent open switch, the operation is more convenient. 5. Equipped with new ek6 earthing switch, which make the operation convenient and the maintenance easily. 6.All switch operation is proceed with the door of high voltage compartment closed. Also the switchgear has the function of forcible closing the door and the safety is higher. The door can endure the inside fault current.

ASN2-24 air-insulated metal-clad enclosed switchgear is a necessary power distribution equipment in 24kV 3-phase AC50/60Hz power system. It is used in power generator, substation, factory and high building as a equipment of receiving and distributing electrical power. Also it is used to control, protect and monitor the circuit. The switchgear accords with the standard of GB3906, DL/T404 and so on. 1. Busbar is covered with shrinkable insulated material or disposed with epoxy, which make the electrode improved and the body of the switchgear compact. 2. The frame of switchgear is made of top quality aluminum-clad zinc plate through rivets and has characteristic of higher strength, rapider assembled efficiency and more artistic appearance. 3. According to functions the trolley can be divided into circuit breaker trolley, voltage transformer trolley, metering trolley, isolation trolley. The same kind trolleys can be exchanged freely. 4. Can be fitted with VN2 series center located high voltage AC vacuum circuit breaker. 5. There are clapboards between function compartments and individual pressure relief passage. 6. The instrument board is with applicable inclined angle so the operation and observation are more convenient. 7. The instrument compartment is a knock-down module, which not only improve the prettiness and safety of secondary wires but also make the maintenance and overhauling more convenient.

Foremost in quality of workmanship and investment in “state of art” technology to manufacture world class LT switchboards, we have established ourselves as a symbol of quality and innovation in this field. The Panels have been successfully tested at CPRI to withstand short circuit levels of 50KA for 1 sec, IP 54 degree of protection & Temperature rise as per international standards. The Design and Engineering department is well equipped with Computer Aided Design (CAD) systems and drafting facilities for accurate and quick preparation of design & execution.
