Insulation Tubing:As part of the Joints, Heat Shrinkable Insulation Tubing is suitable for a variety of low voltage electrical and mechanical applications:
Insulating and sealing systems for power cables have to perform to a range of exacting requirements; to be uneffected by years of weathering and ultra-violet light, to stand up to continuous temperature changes, to keep out moisture and corrosive liquids for a generation, to be immune to oils and solvents, and to combine lasting insulating properties with low weight, toughness, impact strength and flexibility.
The need for modern standards of efficiency and simplicity of installation is a further significant consideration.
To meet these demands, CIAC developed heat shrinkable insulation tubing
now in widespread use in terminations, joints and cable repairs.
Heating with a commonly available gas torch activates the tubing's ¡±elastic memory¡± causing it to recover in diameter. The tubing's high shrink ratio enables it to shrink and tightly fit a wide range of cable sizes and accessories.
CIAC Heat Shrinkable Insulation Tubing is fast and easily installed, and has proven its long term reliability in harsh climatic conditions and polluted environments.
