Introduction of Pre-fabricated Substation.
Pearl Electric's history may date back to the year of 1958 when it is founded as the Panyu Electrical Motor Factory. With more than fifty years development and company restructuring/reorganization in recent years, Pearl Electric is now ready to realize its ambition of becoming a global power transformer manufacturer and supplier.
1) Dig the tunnel---->placing plain concrete---->placing reinforced concrete base, reinforced concrete girder or wall is set on the top---->use mortar to smooth inner and outside surface.
2) G100 steel tube should be buried for the cable inlet and outlet. Its depth should be no less than 0.5 meters. The end of the tube should be made in trumpet shape and is 5/100 inclined outwards, thus to avoid water flowing into the tunnel.
3) The effective air outlet area should be no less than that specified in the drawings provided by manufacturer..
4) The installation base should be even and the inclination should be no more than 10mm, thus to avoid production deformation. The footplate around the base should be inclined towards outside.
Earthing Screen Requirement
1) The earthing conductor should be buried at least 0.6 meters depth into the earth.
2) The welding should be made on both sides and rust-resistant paint should be applied on the welding surface.
3) The resistance of the earth screen should be less than 4 ohms.
