Specification requirements and voltage levels for Outdoor ground wire
- Oct 24, 2018 -

The Outdoor ground wire is mainly used for line and substation construction when it is used. It can effectively prevent the static electric shock from being generated by the adjacent electrified body to some extent or to ensure the safety when the brake is misclosed. The substation outdoor grounding wire has three sets of each set, and each set is connected by a wire end line card, a short circuit line and a ground end line card.

 

When the substation outdoor grounding wire is used, it is grouped and operated. According to the regulations, the power is checked first. After confirming that the power has been cut off, firstly, the grounding terminal card needs to be fastened to the grounding pole, and then the power line voltage level is selected. Stick, hang the wire end card on the wire. After the work is completed, the wire end line card should be removed first, and then the ground end line card should be removed.

 

The Outdoor ground wire of the substation will have different line card form, quantity, and length of the wire due to different voltage levels. Generally, only three wire end card, short wire, ground wire and one ground terminal wire will be used. The cards form a "grounding wire". When using, check the power according to the regulations. After confirming that the power has been cut off, fasten the grounding terminal card to the grounding pole, and then use the corresponding operating rods to hang the wire end card on the wire according to different voltage levels. (Operation bar has fixed and folded type) Remove the wire end line card first, then remove the ground end line card.http://www.wxaqyd.com/
