Compact Substation Inspection Process

1. Compact Substation should meet the following requirements:

  • Inspection certificate and accompanying technical documents, with a factory test records;
  • Visual inspection: Nameplate, completely accessories, insulation items without defects, cracks, part of oil-filled no leak-out, inflatable pressure high-voltage equipment indicating normal, coating integrity.

2. Construction process and description

  • The construction process Laying based steel → laying ground grid →compact substation handling →compact substation installation → cable termination connection.
  • Process Description Laying based steel (1)Indoor base of cable and based platform with 1:25 concrete mortar surface, thickness of 20mm, the surface to be smooth.
  • The basis of steel should be strictly in accordance with the drawings and specifications to lay and be treated with preservatives.
  • Equipment installation of fasteners should be used in galvanized to all products (except bolt outside).
  • After installing basic steel, its top should be higher than the flat ground 10mm, base-steel should have more than two place to reliable grounding.
  • Compact Substation between the base and the foundation to use cement mortar seal so as to avoid rain water into the compact substation ; After the cable into the Compact Substation, the gap between cable and pipe required to waterproof and seal; The bottom of compact substation need to slightly tilted to avoid water
  • The number of inlet and outlet and the cable diameter, can be determined according to the actual situation of the user’s location and the inlet and outlet , spacing of pipe row not less than 30mm.
