Changzeyuan Electronics' busbar heat shrink tubing for LV/HV switchgear and motor busbars, with matching red/yellow/green insulation tubing: environmentally friendly, low smoke, RoHS compliant; good insulation and flexibility; minimum shrink temperature 110 °C; voltage ratings CZY 1T: 1 kV, CZY 10M: 10 kV; excellent insulation, temperature and voltage resistance.
Busbar heat shrink tubing for LV/HV switchgear and motors, with matching red/yellow/green insulation tubing is made from radiation cross-linked modified polyolefin with other additives.
Applications:Busbar heat shrink tubing for LV/HV switchgear and motors, with matching red/yellow/green insulation tubingBusbar insulation in LV/HV switchgear: prevents injury from live bare busbars; avoids short circuits and flashover caused by small animals or conductive objects; prevents corrosion, contamination and flashover; increases insulation margin and allows shorter phase-to-phase and phase-to-earth clearances, enabling more compact switchgear designs.
Shrink ratios: 2:1 and 2.5:1
