Features of wedge type insulation strain clamp
● Insulation Performance: Insulation resistance > 1.0×10¹⁴ Ω; power frequency withstand voltage ≥ 18 kV (withstands voltage for 1 minute without breakdown);
● Grip Strength: Not less than 95% of the calculated breaking force of the conductor; the conductor does not slip easily;
● Structure: Wedge-type self-locking design; no special crimping tools required; easy to install;
● Insulation Cover Weather Resistance: Maintains good performance after 1,008 hours of artificial climate aging testing;
● Applicable Voltage: Distribution lines rated at 10 kV and below.
Environmental Adaptability
Factory direct sales,customization services available
◆ Temperature Range: -30°C to +90°C; withstands extreme cold, intense heat, and large diurnal temperature fluctuations without risk of brittle cracking, deformation, or insulation aging;
◆ Climatic Environment: Suitable for harsh conditions such as high wind and sand, high salt fog, heavy rainfall, and icing; excellent weather resistance with stable performance after artificial climate aging tests;
◆ Corrosive Environment: The aluminum alloy body is oxidation-resistant, and fasteners are hot-dip galvanized for corrosion protection; withstands atmospheric and industrial dust corrosion, suitable for standard outdoor and general corrosive environments; 4. Terrain: Suitable for various terrains including flat land, hills, suburban areas, and farmland; particularly suitable for lines in windy regions, enhancing the line's wind resistance.

FAQ
Q: Can it be used in coastal or high-humidity corrosive environments?
A: Yes, the aluminum alloy + galvanized anti-corrosion structure offers excellent resistance to salt spray and corrosion, making it suitable for harsh outdoor environments.
Q: What is the difference between NXL wedge type insulation strain clamp and NY type tension clamps?
A: NXL is a wedge-type, crimp-free design, while NY is a hydraulic crimping type; NXL allows for faster installation, and NY is primarily used for long-span and ultra-high-voltage lines.
Q: Do line clamps require regular inspection after installation?
A: Yes. Focus on checking whether the wedge is loose, whether the bolts are tight, whether the conductor has slipped, and whether the body has cracks.
Q: What should be done if the conductor slips slightly?
A: Immediately shut down the power supply for repair. Slippage indicates a failure in the clamping mechanism; the clamp must be replaced, and continued operation is strictly prohibited.
Q: Can NXL wedge type insulation strain clamps be used with insulated conductors?
A: They cannot be used directly; insulated conductors require the use of specialized insulated tension clamps.
Q: What is the typical service life?
A: Under normal conditions, the service life can reach 20 to 30 years; with proper maintenance, it can be even longer.
