Ceramic cross arm insulator S-380, S-380Z,SC-380，SC-380Z

Ceramic insulators are a special type of insulation component that can play an important role in overhead transmission lines.
Ceramic insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and operation life of the entire line. Maintenance and upkeep of porcelain insulators: In humid weather conditions, dirty porcelain insulators are prone to flashover discharge, so clean them up and restore the original insulation level. Generally, areas are cleaned once a year, while polluted areas are cleaned twice a year (once before the fog season). 1. Power outage cleaning refers to workers climbing onto poles and wiping them with cloth after a power outage on the power line. If it cannot be cleaned thoroughly, it can be wiped with a damp cloth or washed with detergent. If it still cannot be cleaned thoroughly, the insulator or composite insulator should be replaced. 2. Uninterrupted cleaning is generally carried out by using insulation rods equipped with brushes or tied with cotton yarn to wipe insulators on the operating lines. The electrical performance and length of the insulation rod used, as well as the distance between personnel and live parts, should comply with the corresponding voltage level regulations, and there should be a dedicated person to supervise during operation. 3. There are two methods for flushing with electric water: large water flushing and small water flushing. The flushing water, length of the operating rod, and distance between personnel and live parts meet the requirements of the industry regulations.
