Patawan 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
Kakayahan sa electrical:
Rated voltage na 220kV, angkop para sa cable cross-section na 400-2500mm ², lightning impulse withstand voltage na 550kV (10 beses para sa positive at negative polarity nang may pagkakaiba)
Ang conductor connection ay gumagamit ng molding process, may mababang contact resistance at short-circuit current withstand capacity ≥ 25kA/s
