Material: 25kV high voltage insulated rubber boots / 35kV high-voltage insulated rubber boots 1,25kV high-voltage insulated rubber boots Executive Standard: Q / 12HG6096-2006, in line with GB12011-2009. 35kV high-voltage insulated rubber boots Executive Standard: Q / 12HG3259-2002, in line with GB12011-2000. 2. Scope: electrical insulation rubber boots made from natural rubber processing, it is mainly used as an auxiliary security appliance frequency voltage 20KV-35KV less electricity, electrical equipment maintenance job in construction. 3, performance indicators: level factory inspection (KV) preventive inspection (KV) allowable leakage current (mA) 25kV 25 20 ≤8 35kV 35 30 ≤12 4, the electrical insulation performance testing requirements: (1) is not greater than 4mm metal ball stacking height of not less than 15mm. (2) foreign extremely soaking sponge placed inside metal containers. 5 Note: (1) The products manufactured qualified electrical insulation properties. After the user purchase rubber boots, was found in the transport, storage process to rain, moisture mildew, or other abnormal changes to statutory testing organization should be reviewed electrical performance tests. (2) must be carefully checked before use, if there is any damage should not be used. (3) The job should be set into the boots cuffs, not with various oils, acids, alkalis and anti-corrosive substance contact Fengrui metal mechanical damage. (4) should pay attention to the wearer outsole wear after wear off if the outsole pattern, you should not use. (5) According to national standards, in accordance with the company's original packaging standard storage conditions, quality of 24 months from the date of the prescribed standards of production. More than 24 months shall preventive inspection requirements by only testing electrical insulation properties, in line with the provisions of this standard, may be sold and used.
