Purpose

PAM clamps ensure reliable connections between conductors made from different materials, which is particularly important during modernization or repairs of power lines requiring transitions from copper to aluminum or steel-aluminum conductors.

Design

The clamps consist of two plates that distribute pressure evenly on the joined conductors, preventing damage while ensuring a secure electrical connection.

Installation

The clamps are mounted using a bolt connection, ensuring simple and reliable installation without the need for specialized equipment.

Advantages

• Versatility: Suitable for different types of conductors.
• High mechanical strength: Provides a secure and durable connection.
• Ease of installation and removal: No specialized tools are required.
• Compliance: Meets modern quality and safety standards.

Application

PAM clamps are widely used in the energy sector for constructing and repairing overhead power lines, providing reliable and long-lasting connections between conductors of different materials.
