06. Insulation Resistance:
The cable connector box is encapsulated according to the prescribed operating procedures, and after soaking in 1.5m deep water, the insulation resistance between the metal components at both ends of the cable connector box and between the metal members and the ground is not less than 2x10^4Mω.
07. Voltage resistance:
Operating procedures package, sunk into 1.5m deep water soaking 24h, fiber optic cable connector box at both ends of the metal components, metal components and the ground between 15KV DC action, 1 minutes do not penetrate, no flying arc phenomenon.
Test results：No breakdown, no flying arc phenomenon
