Helical connecting loop clamps, type ССШ-Dпр-3А
Helical connecting loop clamps, type ССШ-Dпр-3A is used for connection of ground wires in the jumper loops of overhead power transmission lines.
Drawing 1 – Helical connecting loop clamp, type ССШ-Dпр-3A for connection of ground wires of the cross-section less then 80 mm ²
Drawing 2 – Helical connecting loop clamp, type ССШ-Dпр-3A for connection of ground wires of the cross-section over 80 mm ²
Helical connecting loop clamp, type ССШ-Dпр-3A for the ground wires of a cross-section over 80 mm² consists of:
- connector made of steel spiral strands;
- armor rods made of separate wire spirals or strands.
Helical connecting loop clamps, type ССШ-Dпр-3A for ground wires of a cross-section less than 80 mm² has only one connector.
