Aluflex Cable Leads for Medium & High Voltage Portable Earthing (MV HV)

Pbwel supply Aluflex portable earthing leads for all earthing applications and are produced from multi-stranded, commercially pure aluminium with an extruded PVC sheath to protect the earthing cable from damage.

Aluflex leads can be supplied in any required length, in a wide range of sizes including specifically for Substation use 150sqmm and 50sqmm according to ENA specification 41-21. The flexible aluminium earth lead comes with tested and approved compression terminations and stress support springs/sleeves.

PBwel Aluflex Leads are used for connecting between a Line End clamp and an Earth End clamp. For use in Substations, Portable Primary Earths always employ 150sqmm Aluflex cables with a transparent PVC sheath. Field Equipment Earths are utilising 50 sqmm, Arctic orange Aluflex leads, 50 sqmm exact leads are used for the control of induced voltages.

The flexible conductor is of a circular cross section made up of commercially pure aluminium wires, giving a nominal sectional area of 150sqmm. Portable earthing leads are also available in blue and green, solid, opaque or semi-transparent coloured PVC sheaths and other colours are available on request.

Portable Primary Earth Leads

Portable Primary Earth leads following the ENA Technical Specification 41-21, 150sqmm Aluflex with clear PVC sheathing. The earth leads are fitted with PB150T terminations and stress relieving springs to reduce flexing, which would otherwise create work hardening of the cable between the terminations and the cable junction.

The Aluflex Leads are carefully manufactured and tested rigorously throughout the manufacturing process to ensure quality and performance. Terminations are made from specially milled and certified material, and precision machined.
