Inside the Conductor:
To water-block the interstitial gaps inside the conductor, specific grades of Tianrong non-conductive and semi-conductive water-blocking tapes are applied between wire layers during stranding. This targeted barrier halts longitudinal water migration from the inside out, strictly isolating moisture damage if an outer breach occurs.
Product selection:
We offer a versatile range of premium materials tailored to your specific application and engineering requirements:
Non-Conductive Water-Blocking Tape: DZSS152, DZSD150
Semi-Conductive Polyester Water-Blocking Tape: BDZSD252
Technical Features and Operational Benefits
High Swelling Performance
Utilizing cable-grade superabsorbent polymers (SAPs), these tapes provide rapid expansion rates upon contact with water and maintain thermal stability under continuous operating temperatures.
Process-Friendly Controlled Breakage
Engineered with sufficient tensile strength to withstand high-speed line feeding, the tape is designed to fracture under the mechanical compression of the stranding process. This structural breakdown ensures direct metal-to-metal contact between the wire layers, preventing increased electrical resistance and maintaining conductor conductivity.
