WHAT IS WATER BLOCKING TAPE

HOW IT WORKS

Cable Damage

Water Tree Phenomenon




In structure of power, telecommunication or fiber optic cables, particularly in the air, underground and underwater, they are all able to avoid water penetration and maintain their main function by applying swellable(water blocking) tape, swellable(water blocking) yarn, and swellable(water blocking)powder in between insulation spaces and sheath.
