NXJ-001-4

Product Features

1. Premium Material Construction

C-shaped Housing: High-strength, oxidation-resistant aluminum alloy, die-cast for structural integrity.

Non-magnetic design eliminates hysteresis and eddy current losses, classified as energy-efficient hardware.

Internal Wedge: Made of weather-resistant insulation-reinforced engineering plastic or high-strength nylon.

Provides superior electrical insulation and mechanical stability.

2. Innovative Wedge Structure

Self-Tightening Mechanism: Wedge design ensures grip force increases proportionally with conductor tension, requiring zero maintenance during operation.

C-Opening Housing: Facilitates easy insertion of the internal wedge and conductor, enabling quick, tool-assisted installation.

Product Advantages

1. Convenient Installation

The cable can be directly installed without stripping the insulation layer, which improves installation efficiency and reduces labor intensity.

2. Excellent Insulation Performance

The internally equipped insulation core ensures electrical isolation between the conductor and tower poles or other metal components, preventing current leakage or short - circuit faults.

3. Strong Adaptability

It is suitable for various specifications of conductors, covering a conductor range of 16 - 300 square millimeters, and can meet the needs of different voltage levels and conductor specifications.

4. Maintenance - Free

Due to its self - tightening characteristics and good insulation performance, it does not require frequent maintenance or component replacement during operation, which can reduce maintenance costs and extend service life.

Functional Features

1.Conductor Fixing

Suitable for the terminals or both ends of tension sections of 10kV and below overhead insulated aluminum core conductors. Used in conjunction with insulator strings, it fixes the overhead insulated conductors on towers or other support structures to ensure the stability of the conductors during operation.

2.Conductor Tensioning

Capable of tensioning the conductors to prevent them from slackening or swinging due to factors such as wind force and temperature changes. This protects the conductors from mechanical damage and maintains the stable operation of the power system.
