Cable support clamp 4x(50-70 mm) SO275S

The SO275S suspension clamp is a reliable solution for permanently fixing messenger wires in low-voltage aerial lines. Its design, based on compression screws with breakaway nut heads, ensures a secure and safe connection. This is a key element of the installation that guarantees the stability and long-term functionality of the line.

Design and application

This clamp is designed to work with conductors with a cross-section of 4x(50-70) mm², making it an ideal choice for installations requiring solid conductor fixing with a core diameter of 11.6 to 13.2 mm. The breakaway nut heads facilitate assembly and disassembly, and also provide an additional element of protection against unauthorized loosening. This clamp is used both in new installations and in the modernization of existing networks.

Parameters and compliance with standards

Made of durable materials, the SO275S clamp provides high resistance to atmospheric conditions and mechanical damage. It meets the requirements of EN 50483-2:2009, which confirms its safety and reliability. The mechanical parameters of the clamp are 25 kN for 4x50 mm² conductors and 36 kN for 4x70 mm² conductors. The screw tightening torque is 47 Nm – it is worth remembering this during installation to ensure optimal clamping force. The weight of a single clamp is approximately 1.16 kg.
