JBLY-001-4 Hangzhou-Type Aluminum Parallel Groove Clamp

JBLY-001-4

Product Features

1. High-Quality Material

Made of oxidation-resistant aluminum alloy, it has good electrical conductivity and corrosion resistance.

2. Toothed Structure

Features a toothed design that increases the contact area with the conductor, effectively piercing the oxide layer on the conductor surface to improve contact conditions.

3. Integrated Components

The clamp components are integrated, preventing parts from falling off during installation and facilitating construction operations.

4. Circular Arc Clamping

Securely holds the conductor with a large-area circular arc surface, minimizing conductor creep and maintaining a stable connection.

Product Advantages

1. Low Contact Resistance

The toothed structure and large contact area ensure a tight fit between the clamp and the conductor, effectively reducing contact resistance and minimizing power loss and heat generation.

2. Reliable Connection

With strong clamping force and low contact resistance, it achieves reliable electrical and mechanical connections between aluminum conductors, ensuring stable power transmission.

3. Convenient Installation

The integrated components and common bolt-fastening design simplify the installation process, improving construction efficiency and reducing installation difficulty.

4. Excellent Insulation Performance

Can be used with an insulation cover. The insulation cover has a power-frequency withstand voltage of ≥18kV without breakdown after 1 minute of pressure holding, and an insulation resistance >1.0×10¹⁴Ω, providing effective insulation protection.

5. Strong Weather Resistance

The aluminum alloy material combined with good surface treatment can withstand UV radiation, rain erosion, etc., maintaining stable performance in environments ranging from -30°C to 90°C. It performs well after 1,008 hours of artificial weathering aging tests.

Functional Features

1. Conductor Jointing and Branching

Primarily used for non-tension jointing and branching of aluminum stranded wires or aluminum conductor steel-reinforced (ACSR) wires in overhead power lines, such as jumper connections at non-straight poles and T-junctions at non-load-bearing connections in power systems.

2. Electrical Load Transmission

As a contact fitting, it can join conductors in parallel to effectively transmit electrical loads, ensuring smooth current flow through the connection points and maintaining normal operation of the power system.
