differences between lead sheathed cables and weather proof cables
Answers
Answer:
Lead was one of the first materials to be used to provide an impervious sheath on electric cables. Lead Sheath Cable. A Lead Sheath is available on many types of wire and cable insulations. This sheath is completely moisture proof and very durable.
Explanation:
Weatherproof line wire consists of single conductor covered with either Linear Low-Density Polyethylene (LLDPE) or Cross-linked Polyethylene (XLPE). Conductors may be compressed or concentric strand of ACSR, AAC or solid, compressed or concentric strand copper.
Answer:
A lead sheath can be used as a chemical barrier in low, medium and instrumentation cables for all kinds of petrochemical projects. The advantages of lead sheathed cables are:
Protection against the entry of hydrocarbons.
Protection against moisture ingress.
Can be used as an earthing or grouding system.
Excellent corrosion resistance.
