Insulated Dynema Pilot Wire — High-Strength Braided Rope for Live-Line and Crossing Work
Manufactured by Suntech Power Tools, a Ningbo-based producer with more than 20 years of experience in power transmission line stringing equipment, this insulated Dynema pilot wire is a high-strength braided rope engineered for live-line operation and conductor crossing. Its synthetic UHMWPE fiber core is sheathed for electrical insulation, making it a safe and efficient replacement for conventional steel pilot ropes.
Product Overview
Dynema (UHMWPE) is the lightest and highest-strength high-performance fiber available. With the same diameter, this braided rope delivers comparable strength to a steel wire rope at less than one-seventh of its weight, so handling is faster and easier on site. The insulated sheath also makes it the ideal choice for live-line working and cable crossing applications where conductivity must be avoided.
Key Features
- Light weight and high strength — less than 1/7 the weight of an equivalent steel wire rope
- Voltage insulation via the protective sheath — ideal for live-line operation and crossing
- High-modulus Dynema core for low stretch and stable pulling
- Soft, flexible braided construction for easy handling and coiling
- Custom diameters, lengths and fittings available on request
