Description |
WT-RT-23 is a highly conformable, self-fusing ethylene propylene rubber (EPR) 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. ASTM Approved & MSDS Certificate

Feature |
1. Can be used with conductors rated at 90℃ with an emergency overload rating of 130℃
2. Physical and electrical properties are unaffected by the degree of stretch
3. A special liner
4. Self-amalgamating EPR rubber tape
5. Non-vulcanizing
6. Excellent electrical properties,resistant to corrosion, chemical and ultra violet light
7. Compatible with synthetic cable insulations
|
Application |
1. Electrical insulation and jacketing in splices of solid dielectric cable up to 69KV.
2. Building stress cones in terminations of solid dielectric cable up to 35KV.
3. Jacketing of indoor terminations.
4. Bus bar insulation and corrosion protection.
5. Jacket repair and restoration in ally types of cable.
6. Moisture sealing application.
|
Installation |
1. Should be always successive half-lapped ;
2. Use highly elongate the tape in critical areas;
3. Use less elongation in less critical areas；
(Normally, the tape is stretched to ¾ of its original width in these less critical areas)
4. When using 35KV to 69KV connection cable, it needs to be elongate the tape all the time.
