| WMTM Medium-wall heat shrink tube |
|
|
 |
Application:：
Medium-wall heat shrink tube is made of semi-rigid polyolefin, with or without adhesive lining. It is designed for applications to seal or protect electrical splices, cable terminations and joints where electrical insulation and waterproof are required. 3:1 shrink ratio allows it easily fit over irregular shape and large connectors.
|
| Optional hot melting adhesive liner for complete environmental protection and insulation. |
| Product Features/Benefits: |
- Shrink Ratio: 3.5:1
- Operating Temperature: -45℃ to 125℃
- Seals and protects cable splices and terminations
- High resistance to impact and abrasion
- Work voltage up to 24KV
- Standard color: black, more colors are available upon request |
