Product Description:
This cold shrink breakout is precision-manufactured with pneumatic expansion technology, enabling fast, tool-free installation without heat guns or open flames. As a professional 3-finger cold shrink breakout, it is specially developed for 12/20kV medium voltage cable systems, delivering reliable performance for power insulation and cable separation.
Designed for 12/20kV 3-core cables (35–800mm²), this cold shrink breakout fits perfectly for indoor/outdoor terminations and middle connectors. Made of high-grade silicone rubber, it ensures strong flexibility and long service life in various working conditions.
This premium cold shrink breakout offers excellent anti-tracking, weather resistance, and long-term sealing, effectively protecting cables from moisture, dust, and corrosion in harsh industrial environments.
Applications:
Our Pneumatic Expanded Cold Shrink Breakout Sleeve is engineered for medium-voltage power distribution and transmission systems, making this cold shrink breakout ideal for 12/20kV 3-core cable terminations and middle joints.
As a key cable accessory in power projects, this cold shrink breakout is widely used in substations, transmission towers, and industrial power networks, providing stable cable separation and insulation sealing for cables ranging from 35mm² to 800mm².
Unlike traditional heat-shrink products, our cold shrink breakout supports fast, tool-free installation in remote outdoor sites and confined urban cable trenches, reducing fire risks and improving construction efficiency.
With outstanding UV resistance and anti-tracking performance, this cold shrink breakout performs well in coastal, high-altitude, and corrosive industrial environments. It also supports cable retrofitting and expansion projects, maintaining IP68 waterproof performance and long-term insulation stability.
