Pakapuluwan ang disenyo ng waterproof:
Nagamit ng dual sealing structure ng copper shell at fiberglass waterproof protection box, puno ng room temperature cured flame-retardant waterproof adhesive (tulad ng 3M 2228 # waterproof tape) upang tiyakin ang matagal na waterproof performance
May built-in stress cone structure (imported silicone rubber prefabricated), optimized electric field distribution, enhanced end sealing effect
Electrical performance:
Rated voltage ng 220kV, suitable para sa cable cross-section ng 400-2500mm ², lightning impulse withstand voltage ng 550kV (10 beses para sa positive at negative polarity respectively)
Ang conductor connection ay nagamit ng molding process, may mababang contact resistance at short-circuit current withstand capacity ≥ 25kA/s
