The highest, by the requirement of the lightning protection of standard YD5098 communications office site Yu earth work design specification, earth resistance should
Less than 10 ohm.In order to grounding resistance is up to standard, earth mat construction have employed substantial amounts of steel, friction reducer, change
The material of product etc, resistance value the most perhaps can be up to standard, but after exposing to the sun and rain, chemical reaction
Later, grounding resistance can also be up to standard？Certainly can not, resistance value can be increasing, and this is to communication equipment
It is immeasurable for causing great harm.
