Provide a full range of 10KV/20KV/35KV heat shrink terminals and intermediate joints (models HSY-35-3.1 to 3.3), suitable for cable cross-sections of 50-400mm ², in compliance with GB11033 standard, with a radial shrinkage rate of ≥ 50%, temperature resistance of -55 ℃~105 ℃, and a 20-year aging life. Through hydrogen sulfide resistance, explosion-proof (ISO 80079-36), and salt spray testing, it is applied in fields such as power, petrochemicals, and rail transit. Typical cases include 8000 hours of trouble free operation of offshore drilling platforms. Support scanning for traceability, provide free cable cross-section matching tools, increase installation efficiency by 65% compared to traditional solutions, and reduce overall costs by 57%.
