Offering a unique collection of High Voltage Tape. â¢Ethylene Propylene Diene Rubber (EPDM) Based Insulating Tape â¢Self â amalgamating. â¢Can be used on all extruded dielectric power cables through 33 kV, underground or overhead, indoor or outdoor. Directions for Use : â¢Prepare cable in usual manner â¢Remove separator from tape and apply half-lapped, stretching tape 100% as is being applied. A 100% stretch is obtained when the tape is stretched enough to reduce its width to approximately two-thirds of the original width primary insulation and jacketing can be done using EPDM tape very easily in making straight through joints and bifurcated joints. The void-free insulation yields moisture proof jacketing. The tape can be used to terminate cables and is recommended in building stress cones. During nesting season and otherwise, power interruptions occur due to bird faults which can be eliminated by using EPDM.
