Product Description

UEJ50-Self-amalgamating insulation tape
 

UEJ50 is EPR (ethylene propylene rubber)
based self-amalgamating insulation tape.
The self-amalgamating property makes it voidfree,
electrical stable build-up and resistant to
moisture penetration. It is suitable for insulating
the termination and joint of polymeric insulated
cable up to 132kV.

                                                                
Features

•  Based on EPR.
•  Normal operation temperature: 90°C.
•  Capable of operation at emergency overload temperature: 130°C.
•  Excellent stretch, moisture, corrosion and chemical resistance.


Standard size

•  19mm×9m, 10m
•  25mm×5m, 10m
•  38mm×9m, 10m
•  Other sizes can be customized as requested


Applications

•  Insulating for splices on power cable from 600V up to 132kV.
•  Primary insulation for building stress cone on power cable from 600v up to 132kV.
•  Cross reference: Plymouth W962.
