Application
Low voltage armoured power cable is a type of electrical cable designed for transmitting electricity at low voltages while providing mechanical protection through an armoured layer.
It is commonly used in various applications, including power distribution networks, industrial installations, underground wiring, and outdoor installations where protection against physical damage is required.
Feature
The cable consists of multiple conductors, typically made of copper or aluminum, which carry the electrical current.
These conductors are insulated with a layer of material, such as cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC), to prevent electrical leakage and ensure safe transmission.
The number of conductors can vary depending on the specific application and requirements.
Standard
IEC 60502-2, BS 7870 or other standard can be customized.
