Features

1. The cabinet is made of aluminum-zinc coated sheet processed by CNC equipment, andisassembled by bolts or rivets. The structure is fully assembled.

2. The switchgear has various functions to prevent misoperation, including preventing the load-bearing handcart from moving, preventing the live closing and grounding

3. The switchgear is equipped with high-performance VS1 series medium-voltage AC vacuum circuit breakers and solid-sealed vacuum circuit breakers.

4. The busbar adopts heat-shrinkable insulation materials and optimized electrode shapes, with a compact cabinet structure.

This switchgear is technologically advanced, with stable performance, reasonable structure, convenient use, and safe and reliable power distribution equipment
