The grounding device refers to the general name of the connected wires that are buried underground and the connection wires between the ground electrode to the device.
Ground device model
Construction and acceptance specifications of grounding device
Article 1.1.1 The surface of the bright ground line shall be coated to use the green and yellow stripes with equal width of 15-100mm width.It is advisable to make a sign on the entire length of each conductor or in each interval or every accessible part.When using a tape, a two -color tape should be used.Article 1.1.2 At the entrance of the building to the inlet of the building and at the temporary grounding site, the white primer shall be brushed and marked with a black mark, which is codenamed "".Article 1.1.3 During maintenance, places that need to be grounded in the circuit breaker room, power distribution room, homeline segment, generator output line, etc. The grounding trunk should be introduced.The wiring board and bolt.Article 1.1.4 When the cable passes through the zero -sequential current transformer, the ground wire of the cable head shall be grounded after the zero -sequential current transformer; from the cable head to a section of cable metal guard and grounding through the zero -sequential current transformer.The line responds to ground insulation.
