NXJG-001-3 Wedge-Type Insulated Strain Clamp

NXJG-001-3

Product Features

1. Excellent Material Quality

The housing is typically made of high-strength anti-oxidation aluminum alloy via die casting, featuring no hysteresis or eddy current phenomena. It has good electrical conductivity and corrosion resistance.

The wedge core is generally made of weather-resistant insulated reinforced engineering plastics or high-strength reinforced nylon materials, ensuring excellent insulation performance.

2. Unique Structure

Adopts a wedge-type structure, where the grip on the conductor is directly proportional to the tension, with self-tightening characteristics.

The housing has a C-shaped open design, making it easy to insert the inner wedge and conductor for convenient installation.

The outlet part is arc-shaped, which can hold the conductor over a large area to prevent conductor creep.

3. Superior Insulation Performance

The supporting insulation cover has high power frequency withstand voltage performance. For example, it can withstand ≥18kV at 1-10kV power frequency without breakdown for 1 minute, with an insulation resistance >1.0×10¹⁴Ω.

It can adapt to environmental temperatures of -30°C to 90°C and has good weather resistance. After 1,008 hours of artificial climate aging tests, its performance remains excellent.

Product Advantages

1. Excellent Energy-Saving Effect

Due to the use of materials without hysteresis loss, it can effectively reduce power loss and is an energy-saving certified product.

2. Simple Installation

The wedge-type structure makes the installation process simple and fast, requiring no complex tools or professional skills. Additionally, the integrated design of components ensures no parts will be lost during installation.

3. Reliable Performance

The clamp has a high grip strength, which can reliably fix the conductor to prevent displacement or detachment under environmental factors. This reduces fault and maintenance needs, thereby lowering maintenance costs.

Functional Features

1. Conductor Fixing

Suitable for 10kV and below overhead insulated aluminum stranded wires (JKLYJ) and other distribution lines. It can fix or tension overhead insulated conductors or bare aluminum conductors on insulators of corner or terminal tension poles to achieve fixation or tensioning of overhead conductors.

2. Insulation Protection

Used in conjunction with insulation covers, it provides additional insulation protection for the line, enhancing the safety and reliability of the line. It can effectively prevent current leakage and electric shock accidents.
