Product name:
Insulating tube Silicone cold shrink connector for cable protection
Description:
Cold shrink tubing is a fast and easy way to weatherproof a RF coax
connection for cell site,Unlike heat shrink tubing,it can create a
permanent seal without applying heat ,so it is also known as
no-heat shrink tubing.
Simply position the pre -expanded tubing over the connection that
the protecting and pull the rip cord,the tubing will shrink and
compresses to form a weatherproof seal.
Features:
1.Simple installation.
2. No tool or heat required.
3. Seals tight, retains its resiliency and pressure even after
years of aging and exposure.
4. Resists acids and alkalies.
5. Resists ozone and ultraviolet light.
6. Operating temperature range- EPDM: -60℃ ～ 150℃.
Silicone: -50℃~200℃
Applications
Primary electrical insulation for all solid dielectric (rubber and
plastic) insulated wire and cable splices rated to 1000volts
Introduction:
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.
