Compliance with Standards
The product is designed and manufactured in accordance with IEC 62271-200,GB/T 3906 and DL/T 404 standards.
Product Features
The switchgear is divided into four functional compartments:busbar compartment,medium-voltage compartment,cable compartment and low-voltage compartment.All compartments are manufactured from high-strength steel and assembled using bolted connections.
The enclosure and internal partitions are metallic and earthed.The design complies with the LSC2B service continuity class,ensuring high service continuity,while the partition class PM partition class provides reliable protection for operating personnel.
The switchgear has successfully passed the internal arc fault test and is classified as IAC AFLR,ensuring a high level of personnel safety.
All operations are carried out from the front of the switchgear.Mechanical indicators on the door clearly display the position and operating status of the withdrawable unit and the earthing switch.The operating devices are ergonomically designed,and integrated mechanical interlocks effectively prevent maloperation.
