结构特点

A、外壳采用进口敷铝锌钢板，经CNC机床加工，并采取多重折边工艺。柜体采用组装式结构，用拉铆螺母和高强度螺栓联接而成。这样使加工生产周期短、零部件通用性强、占地面积少，便于组织生产。

B、产品由主母线室、断路器室、电缆室、继电器室等组成，水平母线采用TMY系列镀锡铜排，采用高强度母线支柱绝缘子及母线套管固定在柜体后上部。垂直母线采用高强度母线，支柱绝缘子固定母排。

C、手车骨架也采用敷铅锌钢板，经CNC机床加工后组装而成，手车与柜体绝缘配合，机械连锁安全、可靠、灵活。根据用途不同手车分断路器手车、电压互感器手车、计量手车、隔离手车。

Structural characteristics

A. The shell is made of imported aluminum zinc steel plate, processed by CNC machine tool, and adopts multiple hemming process. The cabinet body is of assembled structure and connected with riveted nuts and high-strength bolts. In this way, the processing and production cycle is short, the parts are versatile, the floor area is small, and the production is easy to organize.

B. The product is composed of main busbar room, circuit breaker room, cable room, relay room, etc. The horizontal busbar adopts TMY series tinned copper bar, and adopts high-strength busbar pillar insulators and busbar bushing to fix the upper part of the back of the cabinet. The vertical busbar adopts high strength busbar, and the pillar insulator fixes the busbar.

C. The frame of the handcart is also made of lead-zinc steel plate, which is assembled by CNC machine tool processing. The handcart is insulated with the cabinet body, and the mechanical chain is safe, reliable and flexible. According to the use of different handcars, circuit breaker handcars, voltage transformer handcars, measuring handcars, isolation handcars.
