Product name:
220mm EPDM Cold Shrink Tube for Waterproof and Acid Resistant Protection
Description:
EPDM Cold Shrink Tubes are a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre stretched condition. The core is removed after the tube has been positioned for installation over an in-line connection terminal link allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber which contains no chlorides or sulphurs.
Product Features:
| 1:Simple installation,no special tools required |
| 2:No torches or heat required |
| 3:Good thermal stability |
| 4:Seals tight retain its resiliency and pressure even afte prolonged years of ageing and exposure |
| 5:Excellent wet elctrical properties |
| 6:Improved tough rubber formulation to withstand rough backfilling |
| 7:Waterproof |
| 8:Resists fungus |
| 9:resists acidss and alkalis |
| 10:Accommodates a wide range of cable sizes |
