Bare overhead conductors carry bulk power between substations and along distribution feeders. The choice of family is a trade-off between conductivity, tensile strength, weight and corrosion behaviour — and it is decided by the line design, not by a catalogue.

Where an existing line must carry more current without new towers, high-temperature low-sag families — ACSS, TACSR, TAAAC, STACIR and GAP constructions — let the conductor run hotter while keeping sag inside the original clearance envelope.

Every family below can be manufactured to more than one standard, and the same nominal area appears under different code names depending on which table the project is specified against. Send us the standard and the size and we will confirm the construction.

Building wire is the final-circuit layer of an electrical installation — the cable that runs in conduit and tray from the distribution board to the outlet, the luminaire and the machine.

The construction depends entirely on which code the building is wired to. North American projects specify THHN/THWN-2 and XHHW-2 to UL; projects on the British or IEC system specify to BS 6004 or IEC 60227. Both are supplied from the same plant.

Colour coding, print legend and packaging are set to the contractor’s requirement — tell us the code and the colour scheme at enquiry.

Concentric cables carry the neutral or earthing conductor as a layer of wires stranded concentrically over the insulated phase core, giving a compact, mechanically protected construction for secondary distribution and consumer service connections.

Common constructions include single-core and split-concentric service cables to national and utility specifications, with copper or aluminium conductors and PVC or XLPE insulation.

Control and instrumentation cable carries signal rather than power — the tripping, indication, metering and 4-20 mA loops that let a substation or process plant be operated and protected.

Because the signals are small, screening matters: individual screens keep pairs from talking to each other, and an overall screen keeps the outside world out. Armouring is added where the route is buried or exposed.

BS 5308 is the usual reference on EPC substation work; IEC and EN 50288 constructions are supplied where the project is specified to those.

Aerial bundled cable twists insulated cores around a bare or insulated messenger, so an overhead distribution line can run compact, touch-safe and far less prone to faults from vegetation or accidental contact than open-wire construction.

ABC is the default for new low-voltage reticulation in most export markets, and increasingly for medium-voltage covered line wire where a route passes through trees or built-up areas.

We supply to IEC 60502-1, AS/NZS 3560 and NF C 33-209, with drum marking and core identification to the utility’s own specification.

Insulated power cable carries the underground half of a distribution network — substation exits, feeders, service connections and the internal reticulation of industrial sites.

XLPE insulation is the modern default: it runs at a higher continuous conductor temperature than PVC, which means more current in the same cross-section. Armouring — steel wire for multicore, aluminium or steel tape for single-core — is specified where the cable is direct-buried or exposed to mechanical risk.

Constructions are available from low voltage up to 36 kV, single and multicore, copper or aluminium conductor.

Offshore and marine cables are built for the harsh conditions of platforms, vessels and subsea installations — resistant to seawater, mud, oil and mechanical abuse, with flame-retardant, low-smoke and fire-resistant properties for safety-critical circuits.

Constructions follow IEC, IEEE 1580 and marine classification-society requirements for power, control and instrumentation service offshore.

Utilities put fibre on their own transmission routes to carry protection signalling, SCADA and, increasingly, commercial telecom traffic.

OPGW replaces the conventional earth wire with a cable that combines the shielding and earth-fault duty with an optical core — the right choice on new lines and rebuilds, where working at the top of the structure is part of the build anyway. ADSS carries no metal at all, so it can be strung below live conductors on an existing line without a shutdown.

Both are quoted against your span, structure and short-circuit data, with matched suspension and tension hardware.

Solar cable sits outdoors for the design life of the plant, carrying DC at elevated temperature under continuous ultraviolet exposure. Ordinary building wire does not survive that duty.

The electron-beam cross-linked constructions used here are rated for 25 years of outdoor service, remain flexible at low temperature, and are halogen-free and flame-retardant.

We supply to the European H1Z2Z2-K / EN 50618 family and to the North American UL 4703 PV wire family.

Some duties are not covered by a standard catalogue construction: a trailing cable that is dragged across rock every shift, a concentric service cable that has to satisfy a specific utility’s metering practice, or a build to a customer’s own drawing.

Rubber-sheathed flexible cable takes abrasion, oil and repeated flexing that would destroy a PVC or XLPE sheath. Concentric constructions put the neutral or earth as a layer around the phase cores, which some networks require for service connections.

If the construction you need is not listed, send the drawing or the duty description — a large share of what we make is built to a specification rather than picked from a page.
