2026-05-09 10:32:36 View:429
Special cable ties for power grids and wind power are designed as cable fasteners for outdoor strong ultraviolet radiation, wide temperature range, vibration, flame retardancy, and insulation requirements. The mainstream is weather resistant flame retardant nylon cable ties (PA66/PA66W), with core requirements of UL94 V-0 flame retardant, -40 ℃~105 ℃ temperature resistance, UV resistance, high tensile strength, and insulation/corrosion resistance.
1. Core types and materials
a. Weather resistant and flame-retardant nylon zip ties (most commonly used)
Material: PA66 (ordinary)/PA66W (weather resistant and UV resistant), black (required for outdoor use).
Flame retardant: UL94 V-0 (self extinguishing, droplet free, power grid mandatory).
Temperature: -40 ℃~105 ℃ (ultra-low temperature type -45 ℃).
Tensile strength: National standard 4 × series ≥ 18kg, 8 × series ≥ 55kg.
Applicable: wind turbine nacelle, tower, substation, overhead line, photovoltaic/energy storage harness.
b. Specialized derivative type
Low temperature resistant type: -45 ℃, suitable for northern wind farms.
Label zip ties: Integrated labels used for high voltage/circuit identification.
Flexible/Returnable: Temporary wiring, maintenance reuse.
Deltec three piece: ABB, head/hook/body, high-strength and shock resistant.
2. Mainstream specifications (commonly used in power grid/wind power)
Nylon zip tie (length x width x thickness, mm)
200 × 2.5 × 1.1: ordinary type, -30~105 ℃, wire harness/secondary wire.
200 × 4.8 × 1.3: universal type, tensile strength ≥ 22kg, inside the engine room/cabinet.
370 × 7.6 × 1.7: Low/ultra-low temperature type (-40/-45 ℃), tower/outdoor large wire harness.
760 × 7.6 × 1.7: Extra long, large cross-section cable/bridge.
3. Key selection criteria (mandatory for power grid/wind power)
Flame retardant rating: UL94 V-0 (mandatory for the power industry, V-2 is rejected).
Temperature resistance range: Outdoor * * -40 ℃~105 ℃, choose -45 ℃ * * ultra-low temperature type in the north.
Anti UV aging: Black PA66W, outdoor for 5 years without brittle cracking.
Insulation and eddy current: non-metallic priority; Metal cable ties are used for grounding or plastic coating to prevent eddy currents.
Tensile strength: Select according to the weight of the cable, and the vibration zone of the fan should be ≥ 55kg (8 × series).
4. Typical application scenarios
Fan compartment: shockproof and flame-retardant nylon zip ties (7.6mm wide) are used to secure the power/control wiring harness.
Tower/overhead line: UV resistant low-temperature nylon cable ties (-40 ℃) or stainless steel cable ties.
Substation/switchgear: UL94 V-0 nylon zip ties with color coded voltage levels.
Offshore wind power: 316 stainless steel or plastic coated zip ties, anti salt spray corrosion.
