Description
Structure Characteristics
■ Reliable performance.Cabinet all charged body to the ground air gap are ≥125mm insulation pieces of the creepage distance are to meet the requirements of national standards,insulation materials are all epoxy or SMC to improve the insulation level of the switchgear and and mechanical strength,the protection level of IP2X;
■ It is equipped with vacuum circuit breaker inlet and outlet line scheme,which can meet the needs of large system short-circuit capacity,and reliable intelligent protection device,which ensures the realization of various protection functions;
■ Safe and convenient to use.The load switch has a static contact insulating cover,which can prevent arcing short-circuit accidents in the cabinet,and the insulating cover has a removable metal door,which is closed at the same time when the grounding switch is closed,so as to ensure the personal safety of the workers who carry out overhauling and replacing fuses for the switches and other equipments.The whole cabinet is oil-free and non-toxic,so there is no danger of fire or explosion;
■ Long service life,low maintenance workload,easy overhaul;
■ Strong overload breaking capacity,with phase-loss protection function,easy to break 2000A transfer current.
