Stress relief mastics

Features:

1.good bonding strength to the tubing of aluminum,copper,lead and tubing for oil removal and  insulation tubing.

2.insulated cables connectors with good air-tightness,sealing,bonding,weathering resistance, ageing resistance,and electrical property.

Application:stress relief mastics

1.stress relief mastics are used to fill in void space or gaps between the cable joints and terminations. Release electrical stress at the end of polymeric cable joints and terminations to ensure the safe operation of power system.2.The specially designed insulation give excellent compatibility with polymeric cables.3.Used to release electrical stresses at the end of the outer screen in MV polymeric cable joints and terminations to ensure the safe operation of the power  system and can also be used to fill void space and gaps during installation of cable joints and terminations.4.Suitable for applications in power cable termination and joint 15kv,24kv,36 kv.5.Maximum service temperature:90 degree.6.Standard color: light yellow
