Zhongdong Cable supplied a range of low voltage power cables for a mineral export terminal in Sierra Leone, West Africa, to support the project's power distribution requirements.
The supply included 0.6/1 kV aluminium conductor power cables with cross-linked polyethylene (XLPE) insulation and a polyvinyl chloride (PVC) outer sheath. Both steel tape armoured and unarmoured constructions were included, covering various conductor sizes.
The following table highlights selected cable specifications supplied for the project.
| Cable Construction | Rated Voltage | Conductor Configuration | Armour Type |
| AL/XLPE/STA/PVC | 0.6/1 kV | 3 × 240 + 1 × 120 mm² | Steel tape armoured |
| AL/XLPE/STA/PVC | 0.6/1 kV | 3 × 150 + 1 × 70 mm² | Steel tape armoured |
| AL/XLPE/PVC | 0.6/1 kV | 3 × 35 + 1 × 16 mm² | Unarmoured |
| AL/XLPE/PVC | 0.6/1 kV | 3 × 25 + 1 × 16 mm² | Unarmoured |
| AL/XLPE/PVC | 0.6/1 kV | 3 × 10 + 1 × 6 mm² | Unarmoured |
The cable construction designations indicate the main components:
AL: Aluminium conductor
XLPE: Cross-linked polyethylene insulation
STA: Steel tape armour
PVC: Polyvinyl chloride outer sheath
These designations describe the main cable components. Confirm details against the relevant product datasheets and applicable standards.
Steel tape armoured cables incorporate an additional mechanical protection layer. Depending on the cable design and installation requirements, they may be suitable for certain underground installations and industrial applications.
Unarmoured cables have a simpler construction and may be suitable for installations where adequate mechanical protection is provided by the surrounding system and the project specifications permit their use.
The choice between armoured and unarmoured cables should be based on installation methods, mechanical protection requirements, and project specifications rather than conductor size alone.
The supply for this project included both constructions to meet different cable requirements.
Aluminium conductors offer lower weight and can provide a cost-effective solution for low voltage power distribution when properly engineered. Cable selection should account for current-carrying capacity, voltage drop, short-circuit withstand capability, and connection requirements. Aluminium conductors should not be substituted for copper conductors on a one-to-one cross-sectional basis.
XLPE insulation offers good thermal and electrical properties and is widely used in low voltage power cables. The PVC outer sheath provides an additional layer of protection against environmental exposure and handling conditions within the limits of the specified cable design.
For coastal terminals and tropical industrial environments, buyers should also assess whether additional properties, such as UV resistance, termite protection, or enhanced moisture resistance, are required.

Cable standards and designation systems vary across countries and markets. Clear technical specifications help buyers compare quotations accurately and ensure that the selected products meet project requirements.
Before placing an order, buyers should confirm the following:
Applicable standard and rated voltage: Specify the required manufacturing standard, rated voltage, and acceptance criteria.
Conductor material and cross-sectional area: Confirm whether copper or aluminium conductors are required and specify the size of each conductor.
Number and arrangement of cores: Identify the required conductor configuration and the function of each conductor.
Cable construction: Determine whether steel tape armour (STA), steel wire armour (SWA), or an unarmoured design is required.
Environmental requirements: Identify any additional requirements for UV exposure, moisture, termite protection, or other site-specific conditions.
IEC 60502-1 is a relevant standard for certain extruded-insulation power cables, including those rated at 0.6/1 kV. Whether a particular cable complies with this standard must be verified against its specified manufacturing standard and supporting technical documentation.
Founded in 2006, Zhongdong Cable manufactures cables for power infrastructure, industrial applications, construction, and related sectors.
The company operates a production base of approximately 67,000 m², with 30 production lines and 30 testing facilities. Its product portfolio includes low voltage power cables, medium and high voltage power cables up to 110 kV, aerial bundled cables, bare conductors, control cables, rubber cables, building wires, and solar cables.
Clear communication of conductor material, cross-sectional area, insulation, sheath, armour, and applicable standards is essential to supporting overseas cable procurement.
