Finally, it is worth mentioning is: Why is it that the line segment measuring insulation resistance must open line of three-phase drainage lines, then each section were measured three-phase wire insulation resistance? The reasons are: (1) some long lines, lead the way transposition, in the absence of marked A, B, C phase of the case lightning protection and grounding line how to sell, failure to prevent leakage test phase insulation resistance, causing a misjudgment; (2) generating a single-phase deemed incomplete grounding, the ground voltage to the lowest one phase must be grounded phase, so only one phase insulation resistance measurement, but in fact it is possible to measure the leakage fault phase, error-prone; (3) There may be more grounding line and so on. Therefore, lightning protection and grounding wire sales price, when the grounding occurred overhead lines must be carefully testing, to determine accurately, the work can not be sloppy. Overhead wires (JKLYJ) suitable for AC rated voltage 35KV and below overhead power lines in urban high rise buildings and forest areas, such as security requirements occasions overhead wires (JKLYJ) suitable for AC rated voltage 35KV and below overhead power lines using overhead wires (JKLYJ) in urban high rise buildings and forest areas and other safety requirements applicable to the occasion and below rated voltage 35KV overhead power lines in urban areas, such as high-rise buildings and forest areas requiring high security lightning protection and grounding wire occasions how much money, lightning protection and grounding wire, Anhui Electric Group is provided by Anhui Electric Group Co., Ltd .. Anhui Electric Group Co., Ltd. (www.ahecable.com) strong, credible, in Chuzhou bare wires and bare conductor products industry has accumulated a large number of loyal customers.
