（1）For Electric Power Cable
For termination and joint of more than 6kV electric power cable, stress control is needed because an electric field is uniform. Heat-shrinkable tubing with appropriate volume resistivity and dielectric constant make stress control well. And heat-shrinkable tubing with high resistance to weathering not including carbon has good anti-tracking property between electrode and ground. And heat-shrinkable tubing with hotmelt adhesive for low voltage cable joint part provides good insulation and water proofing.
（2）For Busbar Insulation in Switch GearFlexible and flame retardant heat shrinkable tubing provides insulation enhancement and flashover protection for busbar.
（3）For CATV, Mobile Phone Base StationHeat-shrinkable tubing with hotmelt adhesive helps for tightening connectors and cable shrink-back.
（4） For Public work, Bridge Beam, PlantHeat-shrinkable tubing with hotmelt adhesive is used for bridge beams and anchors which prevent a landslide. It is also used for anti-corrosion of electric pipes in chemical plants.
（5）For Buildings, RailwaysFlame retardant heat-shrinkable tubing is used for joint parts of wiring in buildings.
Heat-shrinkable tubing with smokeless, halogen-free, and inner liner of mastic adhesive is used for railways.
