Product Introduction

Blokset switchgear can be applied to all places that require high reliability low-voltage power supply systems, including distribution centers, power control centers, etc. It can be widely used in industries: metallurgy, paper-making, manufacturing, and mining; buildings: shopping malls, hotels; infrastructure: various fields such as water treatment, airports, ports, etc.

Main structural features

  • The basic framework of Blokset switchgear is assembled from standard prefabricated components.
  • These components have various specifications and can be assembled into frames of different sizes.
  • The switchgear is divided into four different compartments, namely: ① busbar compartment, ② component compartment, ③ outgoing cablecompartment, and ④ auxiliaries compartment.
  • A switchgear contains 40 modules, and each module is 50mm high.
  • The cabinet has two types: fixed compartment and drawer type.
