Product Overview
The utility of Medium Voltage Lead Sheathed Cables is primarily in land‑based functions in the petroleum, oil, gas, and chemical industries.
MV Lead Sheathed cables are provided with an impermeable and watertight lead alloy sheath to counter the corrosive effect of chemicals involved in these industries, where the lead sheath thickness complies with IEC 60502‑2. The lead sheathing’s resistance to sulfides, water, oil and corrosive chemicals found in the groundwater gives these cables an extended lifespan, making them a reliable option for large‑scale, infrastructure‑related uses.
Standard: IEC 60502‑2
