4G communications base station insulated tube is a series of insulated rubber sleeves which are factory expanded and assembled onto a removable core. T cold shrink tubes are supplied for field installation in this pre-stretched condition. The core is removed after the tube has been positioned for installation over a cable connection, terminal lug, etc., allowing the tube to shrink and form a waterproof seal. It is made of Silicone rubber material, which have excellent weather resistance, acid and alkali resistance. The insulated tube is ideal sealing material for the communication cable, coaxial cable, medium voltage and low voltage power cables.

Compared with heat shrinkable tube, it is not hard and brittle even if used for a long time, and it also can be tight seal and no crack in the case of Cold shrinkage and thermal expansion. It can be used in more harsh environments


  1. Used in 4G communications base station such as cell tower and?terminals, connectors, antenna.
  2. Used in the protection of medium voltage and low voltage power cables and sealing for communication cable and optical cable.
  3. Waterproof and moistureproof for the joint and terminal of cable, optical cable.Insulation of secondary splices, copper or aluminum conductors.
  4. Used in indoor and outdoor, overhead and underground, etc.
  5. Applied to the tool handle, pipe repair or other types of seals, etc.


  1. Simple installation, no need special tools or heat, no need hot?melt?adhesive or adhesive tape to strengthen seal
  2. Suitable for a wide range of different specifications of cable connection seal, can be used in indoor and outdoor, overhead, in the water or buried etc. below 1000 v power cable;
  3. Retains its resiliency and radial pressure even after prolonged years of ageing and exposure, seal tight, still good performance for waterproof, moisture-proof, dustproof;
  4. Good performance for sealing even strong wind;
  5. Salt-fog resistance, acid and alkali resistant, zone?aging resistant?, Good weather resistance, ultraviolet ray ageing resistance.
