Waterproof Function Test Of Parallel Groove Cable Clamp

However, the waterproof function of pg clamps is theoretically completely fine, because single bolt parallel groove connector has undergone an underwater 6KV withstand voltage test at the Electric Power Research Institute, the High Voltage Electrical Research Institute, and the Product Quality Supervision and Inspection Bureau. The test process is to put the parallel groove clamp cable directly into the water and energize it, and there are fish in the water. After 24 hours of power on, the fish are still very active, which proves that the waterproof structure of parallel groove connector is successful.
