Medium Voltage Switchgear
KYN28A-12(24)kV indoor AC metal shield mid-set switchgear is a new generation of advanced medium voltage switchgear. It is applicable to power system with 12kV and 24kV of three-phase AC rated voltage and 50 (60) Hz of rated frequency. It is mainly used in power plants, industrial and mining enterprises and electrical power systems to receive and distribute electric energy, and to control, protect and monitor circuits and start high-voltage motor. The skeleton is made of aluminum-zinc-coated steel plate processed by precision CNC machine tools and through double-layer superimposed inward folding process, with high-strength rivet splicing, precise coordination and high mechanical strength.
UniSafe 12kV metal clad withdrawal switchgear is ABB's global synchronous product, with operating experience around the world, reliable operation, low maintenance, rated voltage and frequency of 12kV, 50 (60Hz) respectively. It is mainly used in factories and electrical power system to receive and distribute electrical energy. The perfect mechanical interlock ensures the safe operation of the electrical power system. The scheme design is flexible and can meet the different requirements of users. It is equipped with ABB VD4 (or iVD4) high-performance circuit breaker, which can be quickly interchanged, reducing unexpected power failure time and improving production efficiency.
MVnex 12(24)kV indoor AC metal shield mid-set switchgear is a product customized by Schneider with the rated voltage and frequency of 12(24)kV, 50(60Hz) respectively. It is mainly used in factories and electrical power system to receive and distribute electrical energy. MVnex is well-designed and has superior performance. It is equipped with high-performance Schneider HVX solid-sealed pole-type vacuum circuit breakers with high parameters and complete solutions, which can meet the needs of different users and industries. Its intelligent solution can realize intelligent functions such as online monitoring, active operation and maintenance, clairvoyance, and intelligent prefabrication.
The HV inverter (soft start) bypass switchgear developed and designed by AHDRE is a 3.6~12kV, 50 (60) Hz bypass power supply device. It is mainly used for the bypass of HV motor frequency conversion (soft start) control cabinets in power plants, water plants, industrial and mining enterprises, etc. It has superior performance and perfect “five-protection” interlocking function. Different options can be provided according to user requirements, such as: manual bypass cabinet with three isolation switches, three contacts (circuit breakers), three contactors (circuit breakers) with two isolation switches, three handcart-type contactors (circuit breakers) and other automatic bypass cabinets, which can also be expanded into one to two, one-to-three manual (automatic) bypass cabinet.
