Application: BHT is the transparent heat shrinkable tubing made by Polyolefin, with adhesive lining to protect splices from water and corrosion. It provides strain relief and anti-vibration in rugged environment, and completely insulates and protects electrical connections. The high purity copper tube provides excellent conductivity. It offers long duration performance, easy installation, and low installing cost, which is more reliable than conventional crimp terminals. Characteristics: ●Shrink ratio: 3:1 ●Excellent conductivity property ●High transparency, High tensile strength ●Excellent stretch and mechanical damage resistance ●High elasticity assures steady performance ●Water proof and moisture resistance ●Operating temperature: -55℃-125℃ ●Minimum shrink temperature: 180℃ Materials ●Insulation: Polyolefin ●Terminal body: Copper |
