Bus bridges, busbars E'mi SHM, SHPZ (R), TKP (R), etc.

SHM with rigid bushing in AC or DC circuits, SHZP (R) with a voltage of up to 1 kV, TZP (R) with a voltage of up to 35 kV are designed to perform electrical connections of switchgears of power plants and transformer substations of power systems, industrial enterprises, oil fields, agricultural enterprises, etc.

Bus bridge housings are made of an open design (Ip00), the bottom of the housing is protected by a shell. Bus bridges, busbars, current lines are assembled from sections with bolted busbar connections and housings. The section housings are welded metal structures made of bent steel profiles and sheet steel, coated with powder paint.

Depending on the configuration and purpose , the sections are divided into:

• straight - forward;
• corner;
• with current transformers;
• with walk-through insulators;
• with surge arresters;
• with compensators;
• with phase rotation;
• with phase transposition;
• tee;
• connections to cabinets;
• connections to transformers, etc.
