How to install high voltage insulators correctly and safely

   Safety measures for installing high-voltage insulators, production must exit the re-closing of the work line, and obtain a scheduling permit to work properly. Before the start of field work, the insulation tool must have a 2500 volt megohmmeter to measure the insulation resistance test electrode width: 2cm, and the maximum spacing: the resistance value of the 2cm insulation tool should not be less than 700 ohms.


Leverage and equipotential personnel must wear a full set of qualified protective clothing. Field personnel must wear safety helmets and workers must not lose seat belt protection. During operation, the staff on the pole must not touch the high-voltage insulator, and it is not from the fire line; the operator must maintain the equipotential grounding safety distance: 110KV 1.0m; 220V, 1.8m; the safety distance of the adjacent phase: 110kV- -1.4m; 220V 2.5m insulation tool maintains effective insulation length, operating rod: 10kv--1.3m; 220kv 2.1, insulated rope and bearing tools: 110kV--1.0m; 220kv - 1.8m, composite insulator zero value detection The operations that must be performed before, as well as the number of good high-voltage insulators must be: 110kV--5 pieces; 220kV - 9 pieces can be charged.


    Insulation breakdown shall be carried out using test instruments, tools and field tests, maintaining sufficient safety distance for different potential discharges, and strengthening supervision. Electrostatic induction electric shock rod personnel shall shield the complete wear of clothing, such as potential drop equipotential operators should use fitness rope insulation protection. During the process, the insulation board breaks the mitigation action and avoids the impact. After the tool is emphasized, the connection between the insulator string and the conductor can be removed after inspection and confirmation.
