Product details
[Product Description]: It is formed by impregnating and drying the water blocking tape with semi conductive adhesive. The fibers have been thoroughly combed, resulting in high longitudinal strength and low resistance.
[Application]: Semi conductive resistance water tape is suitable for use as a semi conductive resistance water layer in waterproof medium, high, and ultra-high voltage power cables and other control, communication, signal, and instrument cables with shielding requirements, serving as a water blocking, buffering, and shielding function.
