Description
Overview

The switching station is an important auxiliary power supply facility in medium-voltage power distribution networks, acting as the downstream hub of ring network power supply systems.

It undertakes voltage transformation, circuit distribution, fault isolation and flexible power supply switching. It can effectively optimize regional power grid topology, shorten power supply radius, and greatly improve power supply reliability and power quality. Widely applied in urban & rural power grids, industrial parks and residential communities, it is also known as an outdoor cable branch distribution station.

Application Areas

Reasonable power supply range division in distribution networks ensures stable and reliable power supply for ring network, branch and terminal loads. Its switching operations will not interfere with normal grid operation and user power consumption.

Meanwhile, it optimizes grid structure, narrows power failure fault scope, reduces line loss and grid operation load, and realizes flexible zoning coordination between power feeders and load sections.

Use Conditions
  1. Ambient temperature: -35℃ to +40℃
  2. Maximum installation altitude: ≤ 2000m above sea level
  3. Relative humidity: daily average ≤95%, monthly average ≤90%
  4. Seismic resistance grade: Grade 8
