Heat-Shrink Busbar Tubings

Property Specification
Type: Heat-Shrinkable Busbar Insulation Tubing / Medium-Voltage Single-Core Cable Sleeve (6/10 kV – 8.7/15 kV Series)
Features: Formulated from high-grade polymeric materials offering superior dielectric insulation, flexible flame-retardant performance, and robust anti-corrosion defense. Provides reliable waterproof encapsulation and mechanical securing for conductor branches through uniform high-temperature contraction. Produced under strict 6S quality control protocols to ensure zero-defect dependability. Recommended for installation in dust-free indoor/outdoor environments with ambient temperatures above 0°C and relative humidity 75%.
Applications: Engineered for busbar insulation, switchgear line protection, and environmental branch sealing on 6/10 kV and 8.7/15 kV single-core XLPE power cable systems. Widely utilized across power generation and distribution utilities, electronic equipment, petrochemical facilities, telecommunications networks, and industrial construction.
