Notes
Air ambient temperature: 30ºC
Ground ambient temperature: 20ºC
Conductor operating temperature: 90ºC
Where a conductor operates at a temperature exceeding 70ºC, it must be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature (see Regulation 512.1.2 of the 18th Edition of IEE Wiring Regulations).
Where cables in this table are connected to equipment or accessories designed to operate at a temperature not exceeding 70ºC, the current ratings given in the equivalent table for 70ºC thermoplastic insulated cables (Table 4D4A) must be used (see also Regulation 523.1 of the 18th Edition of IEE Wiring Regulations).
The above table is in accordance with Table 4E4A of the 18th Edition of IEE Wiring Regulations BS7671 and IEC 60364-5-52.
In an era where reliable electricity is the backbone of modern society, the choice of power cables can make or break infrastructure projects. Enter the BS 5467 Sectoral Shaped Copper Conductor Multi-Core SWA 1.9/3.3kV Cable—a robust, high-performance solution designed for demanding environments. This cable, compliant with British Standard 5467 and IEC 60502-1, represents a pinnacle of engineering in low-to-medium voltage power transmission. With its sectoral shaped copper conductors, cross-linked polyethylene (XLPE) insulation, and galvanised steel wire armour (SWA), it offers exceptional durability and efficiency.
Construction and Materials: Building for Durability
The BS 5467's construction is a masterclass in material science, blending conductivity, insulation, and protection. The conductor is Class 2 sectoral shaped stranded copper, optimizing space in multi-core designs for better current flow and reduced skin effect losses.
Insulation uses XLPE, a thermoset polymer cross-linked for superior thermal and mechanical properties over traditional PVC. It withstands 90°C continuous operation and 250°C short-circuits, ideal for high-load scenarios. A polyester tape separator prevents moisture ingress, while PVC filler maintains structural integrity.
The SWA—galvanised steel wires—provides mechanical armour against impacts, rodents, and abrasion, crucial for underground burial. The outer PVC sheath adds UV resistance and flame retardancy per IEC/EN 60332-1, with a black color for easy identification. Cores are color-coded brown, black, and grey for straightforward installation.
The minimum bending radius of 12 times the overall diameter ensures flexibility without compromising integrity. Voltage rating of 1.9/3.3kV suits auxiliary control and power in networks up to 3.3kV.
Applications and Usage Scenarios
Versatility defines the BS 5467 Sectoral Shaped Copper Conductor Multi-Core SWA 1.9/3.3kV Cable. It's primed for power networks, underground in free-draining soil, outdoor/indoor use, and cable ducting. In industrial settings, it powers machinery; in utilities, it distributes electricity reliably.
In renewable energy, its robust design supports solar farms and wind turbines, where exposure to elements demands armoured protection. Buried installations minimize visual impact in sensitive areas, while XLPE insulation handles variable loads from intermittent sources.
Urban infrastructure benefits from its theft-deterrent SWA, a growing concern globally. In data centers or hospitals, it ensures uninterrupted power for critical systems.
Advantages and Benefits Over Alternatives
Compared to unarmoured cables, the BS 5467's SWA offers unmatched protection, extending lifespan in harsh environments. XLPE outperforms PVC in heat resistance, reducing derating needs and energy losses. Its sectoral shape allows compact multi-core bundles, saving space and material costs.
Environmentally, UV-resistant PVC and flame-retardant properties enhance safety. Compliance with international standards simplifies global procurement, while low DC resistance boosts efficiency, cutting operational expenses.
