Overview The 12KV wall bushing is an epoxy resin APG process pressure gel forming structure, and the size of the external structure is 128 (100×100) mm and the height is 225 mm. It is mainly used in complete sets of equipment with a rated voltage of 10KV and below for insulation isolation and excessive connection. The casing is resistant to dirt and moisture, no special maintenance is required, and only the surface dirt is cleaned regularly. The busbar passes through the hole during installation. Conditions of Use 1. Indoor installation; 2. The altitude does not exceed 1000M; 3. Ambient air temperature +40ºC~5ºC; 4. When the air temperature is +20ºC, the relative humidity will exceed 85%; 5. There is no place where gas, steam, dust and other explosive and corrosive media that seriously affect the insulation of the contact box.
