 WT-RT-23 is a self-amalgamating ethylene propylene rubber (EPR) tape, also called high voltage insulation tape or splicing tape, used on solid dielectric cable for electrical insulation and jacketing in splices up to 69KV and for building stress cones in terminations up to 35KV. The tape comes with a separator that is removed during the taping process. Its 0.76mm thickness and quick amalgamation facilitates a rapid, void free insulation build-up that is electrically stable and moisture proof. WT-RT-23 is suitable for use with conductors rated at 90℃ with an emergency overload rating of 130℃. The tape is also resistant to corrosion, chemical and ultra violet light. |
