Features
● Insulation Performance: Insulation resistance > 1.0×10¹⁴ Ω; power frequency withstand voltage ≥ 18 kV (no breakdown after 1 minute of sustained voltage);
● Grip Strength: Not less than 95% of the calculated breaking strength 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.

Technical Analysis
Our factory & quipment
● The core advantage of the NXL Wedge Strain Clamps for Insulation Cable lies in its wedge-type self-locking structure. When the conductor is under load, the wedge core automatically moves along the inclined surface, achieving a self-locking effect where "the greater the force, the tighter the grip." No specialized crimping tools are required, ensuring convenient and efficient installation;
● Made of non-magnetic aluminum alloy, it has no hysteresis loss and is an energy-saving certified product, reducing power losses in the line;
● The large-area curved clamping design reduces conductor creep, prevents conductor damage, and extends the service life of the conductor;
● The insulation cover has excellent sealing performance and high insulation resistance, effectively preventing potential electrical leakage hazards;
● The streamlined, lightweight design allows for quick installation between anti-vibration hammers and crimping tubes, making it suitable for retrofitting older lines while enhancing wind resistance and operational convenience.

FAQ
Q: What is the main material of the NXL Wedge Strain Clamps for Insulation Cable body?
A: The body is made of high-strength cast aluminum alloy, the wedge is made of aluminum alloy or engineering nylon, and the fasteners are hot-dip galvanized steel.
Q: What surface treatment processes are used?
A: The aluminum alloy body undergoes anodizing, and the fasteners are hot-dip galvanized, providing strong overall corrosion resistance and making them suitable for long-term outdoor use.
Q: What type of Wedge Strain Clamps for Insulation Cable is the NXL?
A: It is a wedge-type self-locking tension clamp that clamps the conductor using the wedge's self-locking principle, requiring no crimping.
Q: Is crimping required during installation?
A: No, it features a crimp-free design. Simply insert the conductor and lock the wedge for quick and easy installation.
Q: Can you provide custom or non-standard hardware?
A:Yes. We design and manufacture non-standard hardware, special-shaped hardware, modified hardware, and specialized clamps based on engineering drawings, technical specifications, or on-site conditions.
