EI 5038 Lightning Cable
A specially-designed cable to convey the lightning current to ground safely
From the lightning terminal, the lightning current is then discharged to earth safely via a uniquely designed EI 5038 Lightning Cable. This is no ordinary shielded cable. It completes the task of conveying the lightning current to ground without electrification of structure, side-flashing (lightning current flashing to nearby conductive objects), touch potential and transferred potential.
This is what the EI 5038 cable is made up of. It has five layers beginning with a centre core made of a polymeric insulation material, surrounded by a 50 mm2 copper wire, followed by a 5 mm-thick primary insulation, then a 38 mm2 copper wire. All are encased within a 3.5 mm-thick sheath.
This durable cable is flame retardant (in accordance with IEC 60332-1-2), halogen free (in accordance with IEC 60754-1) and has low smoke emission (in accordance with IEC 61034-2). To top that, the outer sheath is non-conductive and can withstand long-term ultraviolet radiation (in accordance with GB/T 14049).
With such high material and quality standards, EI 5038 has a ±280 kV impulse rating between the inner and outer copper conductors and a ±100 kV between the outer conductor and the sheath outer surface (based on the IEC 60230 test standard). The voltage breakdown of this cable is almost impossible as the capacitance of the cable can store the energy from the lightning temporarily and thereafter releases it when the current peak is over.
To maximise the performance of the LPS® EI 5038 Lightning Cable, it must not be subjected to bents of less than 0.4 metre radius. The cable must also not be enclosed in any magnetic material such as Galvanised Iron (GI) conduits. It should be kept at least 1 metre away from ELV cables or equipment and at least 300 mm away from a single core power cable.
