Detail
Size specification
| Introduction | |||
| The two-layer composite heat-shrinkable tube is made by composite co-extrusion of thermoplastic insulating material and rubber elastomer insulating material. The rubber elastic body design, when heated, the shrinkage response is fast, avoiding overheating damage. It is suitable for insulation protection of the middle connection of power cables of 36kV and below. | |||
| Fearures | |||
| Operating temperature：-55~105℃ | |||
| Minimum full shrinkage temperature：150 ℃ | |||
| Voltage level：6~36 kV | |||
| Both layers are red insulating layers | |||
| Halogen-free and environmentally friendly, especially thick wall thickness | |||
| Color: red |
