Introduction

Prefabricated substations are defined as type-tested and used to transfer electrical energy from high-voltage systems to low-voltage systems or from low-voltage systems to high-voltage The equipment for power transmission of the system usually includes transformers, low-voltage and high-voltage switchgear, connecting wires and auxiliary equipment installed in the enclosure. This Substations are installed in publicly accessible locations, and personal safety is guaranteed in accordance with the prescribed conditions of use. This means that in addition to the specified characteristics, ratings and related test procedures, special attention should be paid to the provisions on personal protection, including operation People and the general public. This protection is ensured by the use of type-tested components as well as reasonable design and the structure of the housing. Pre-installed Th......
