BS6724 Cable Description
BS 6724 often specifies the use of materials like Cross-Linked Polyethylene (XLPE), Ethylene Propylene Rubber (EPR), or thermosetting polyolefin insulation.
They are designed for use as LSZH armoured mains cables in public areas where there is a need to reduce the risk of harmful smoke and fumes when exposed to fire. Mainly used in low voltage power and control applications such as buildings, industrial environments and underground facilities
BS 6724 cables are typically armored, providing additional mechanical protection against damage in various environments. The robust construction, including the armor, makes BS 6724 cables suitable for direct burial in the ground.
The standard covers a range of core configurations, including single-core, two-core, three-core, four-core, and five-core cables.
