SUBSTATION EARTH LEADS
P&B Weir Electrical Ltd supply Substation Earthing Leads with Aluflex cable for all earthing applications, all of our 150sqmm terminations are embossed with our name to ensure the highest quality. Aluflex earthing leads (ESI-C1-2T1) are produced from multi-stranded, commercially pure aluminium with an extruded pvc sheath to protect the cable from damage.
The flexible aluminum earth leads come with tested and approved compression terminations and support sleeves which are used for connecting a line end clamp and an earth end clamp. The flexible conductor is of a circular cross section made up of commercially pure aluminium wires, giving a nominal section area of 150sq.mm.
Leads are also available in blue and green, solid, opaque or semi-transparent coloured pvc sheaths for special applications on request.
Leads for Field Earths generally use two types of terminations. One end is PB150T which is suitable for the CE20 Clamp to connect to the Substation Earth Tape, whereas the other is a standard PB50 Palm Termination with a 13.5mm hole. Where a CE20 Earth End clamp is not fitted one end a lead having two PB50 palm terminations may be used.
Further technical details
Aluflex Leads are designed to meet specific requirements of ENA technical specification 41/21
For use in Substations, 150EL is always used as a primary lead. 50EL Arctic Orange is used for Field Equipment Earths, and for the control of impressed voltages.
DSSB-SLE-PEE-150EL is suitable for the CE20 clamp. DSSB-SLE-PEE-50EL is a standards for other clamps.
