CAPG PG Clamp

A CAPG PG Clamp (Copper-Aluminum Parallel Groove Clamp) is a specialized type of electrical connector used to join copper and aluminum conductors in power distribution systems. This type of clamp is designed to ensure a reliable and durable electrical connection between conductors of different materials.

Product Description

Product Introduction:

The CAPG PG Clamp are connectors for connecting cables or wires arranged side by side or parallel with copper and aluminum. It is usually used in transmission lines, substations and industrial and mining enterprises.

Product Details:

  • Material: Select oxidize-resistant aluminum alloy for the body and teeth-shape structure, ensuring durability and low resistance contact.
  • Insulation Cover: Provides exceptional electrical insulation, tested for high voltage endurance and resistance to environmental aging.

Structural Features:

  1. Oxidize-Resistant Aluminum Alloy: The clamp body is made from a special aluminum alloy that resists oxidation, maintaining conductivity and a long service life.
  2. Teeth-Shape Structure: Features a teeth-shape design that ensures low resistance and reliable electrical splicing.
  3. Interlocking Parts: All parts of the clamp are interconnected, preventing loss of components during installation.
  4. Arc Embrace: An arc design securely holds the conductor in place, preventing movement or displacement.

Insulation Cover Performance Features:

  1. Withstand Voltage: Capable of withstanding 18kV for one minute without breakdown, ensuring electrical safety.
  2. Insulation Resistance: Exhibits high insulation resistance, rated at greater than 1.0 x 10^14 ohms.
  3. Weather Proof Performance: Demonstrates excellent weather resistance after 1008 hours of artificial climate aging tests, maintaining performance in harsh conditions.

Installation Process:

  1. Conductor Preparation: Prepare the conductors by cleaning and measuring the required length for connection.
  2. Clamp Assembly: Assemble the CAPG PG Clamp around the conductors, ensuring the teeth-shape structure is properly aligned for optimal contact.
  3. Insulation Cover Installation: Secure the insulation cover over the clamped area, ensuring all parts are interconnected and no components are loose.
  4. Verification: Test the clamped connection for electrical continuity and insulation integrity.

Applicable Environmental Conditions:

  1. Operating Temperature Range:
    • The clamp is typically designed to function within a specific temperature range, such as -40°C to +105°C, which allows it to be used in various climates without performance issues.
  2. UV Resistance:
    • It should be able to withstand prolonged exposure to ultraviolet (UV) light, which is crucial for outdoor applications. The insulation cover’s UV resistance might be quantified by a specific duration of exposure without degradation.
  3. Chemical Resistance:
    • The clamp’s materials should be resistant to common chemicals, such as acids, alkalis, and solvents, which is essential for environments where chemical exposure is possible.
  4. Humidity and Wet Conditions:
    • The insulation cover should maintain its integrity and insulation properties in high humidity environments or after exposure to water, which can be tested by specific IP (Ingress Protection) ratings.
