Electrical cables carry power and control signals between supply networks, equipment, and installations. Cable Services stocks low voltage, medium voltage, and high voltage cables across 6 UK branches, with same-day cutting and DNO/IDNO approved utility ranges held in depth.
What are electrical cables?
An electrical cable is one or more insulated conductors held within a protective sheath. The conductor is usually copper or aluminium. The insulation is usually PVC, XLPE, EPR, or LSZH. Cable Services stocks 3 voltage classes. Examples include SWA armoured cable, twin and earth cable, 6491X panel wiring, and 11kV XLPE utility cable.
Electrical cables are grouped by voltage rating. Cable Services stocks 3 classes: low voltage up to 1kV, medium voltage from 1kV to 35kV, and high voltage above 35kV. Each class below links to its full stock range.

Cable Services holds extensive stocks of LV and 11kV DNO and IDNO approved cables for utility connections. The table below sets out the stocked utility ranges by category and construction.
| Utility category | Construction and standard |
|---|---|
| LV service cables | Aluminium and copper, single and three core, straight and split concentric, PVC and LSOH |
| LV waveform cables | Three and four core, PVC and LSOH |
| 11kV DNO cables | Aluminium, single core, XLPE, unarmoured, triplex stocked |
| MV armoured cables | BS6622 and BS7835, 3.3kV to 33kV, single core AWA or 3 core SWA |
Cable selection depends on 4 factors: voltage rating, current load, installation environment, and the governing standard. The tools below size and specify the correct cable for a project.
Cable Services runs an automatic winding and measuring cable cutting machine at the Wrexham facility. The machine cuts cable to exact length, which removes full drum waste and reduces project cost. Kitting bundles cut cable with the matching glands, joints, and accessories for each job.
The cable ranges above pair with the jointing, glands, lugs, and cleats needed to install them. Common questions on electrical cable types, standards, and supply are answered below.
What is the difference between LV, MV, and HV cables?
Voltage rating sets the difference. Low voltage cables operate up to 1kV. Medium voltage cables operate from 1kV to 35kV. High voltage cables operate above 35kV. Higher ratings use thicker insulation and screening.
What is the most common low voltage cable type?
Twin and earth cable is the most common low voltage type in UK fixed wiring. SWA armoured cable is the most common type for buried and external power circuits. Both are stocked in multiple sizes.
Can electrical cable be cut to length?
Yes. Cable Services cuts cable to exact length on an automatic measuring machine at Wrexham. Cut lengths remove full drum waste. Kitting adds the matching accessories for the circuit in 1 delivery.
What does LSZH or LSOH mean on a cable?
LSZH and LSOH mean low smoke zero halogen. The sheath emits low smoke and no halogen gas when exposed to fire. These cables suit enclosed spaces, public buildings, and rail.
Which standards apply to armoured power cables?
Low voltage armoured cable follows BS5467 and BS6724. Medium voltage armoured cable follows BS6622 and BS7835. Insulation follows IEC 60502 for 600/1000V and rated MV constructions.
