Any cable system needs a secure connection and protection. Whether it is an overhead transmission line or an underground telecommunications network, the signal and power distribution depend heavily on the cables. While the overhead power lines use aerial bunched cables for insulation and efficient power transmission across the power grid, the underground cables need further protection due to more demanding conditions. These cables use an armoured sheath of aluminium for this purpose. We at Paraflex are an Alu Arm Cable manufacturer, providing robust solutions for various underground cable networks.
Understanding Alu Arm Cable
The Alu Arm cable, the ‘alu’ refers to aluminium and ‘arm’ is short for armoured. It means an armoured sheath of aluminium metal is wrapped around the cable. There is a key reason why aluminium armoured cable is used in underground cable systems. The underground cables are subjected to various testing conditions, like moisture, sudden impact, continuous mechanical loads, soil conditions, etc. With the armoured protection, these cables are secured from all the damaging factors.
An Alu Arm Cable manufacturer follows a standard design in the construction of these cables. Multiple bunched copper wires are given XLPE (cross-linked polyethylene) insulation. A binding metal binds the conductors together, with the addition of filler. The inner sheath of PVC wraps the binding tape. The aluminium metal sheath is layered over the inner PVC sheath for armouring. The whole assembly is finally insulated by an outer PVC sheath.
Benefits of Alu Arm Cable
Equipped with robust mechanical protection, the Alu arm cable is used in various underground cable systems to distribute electricity in commercial, industrial and residential places as well as exchange signals in telecommunication networks. Here are the benefits of an Alu arm cable:
- Protection against mechanical damage due to continuous or impact load.
- Resistance against moisture, water and heat in the underground.
- Rust, corrosion, chemical and abrasion resistant.
- Reliable service with less need for repair and maintenance.
- Also protects against rodents and other underground creatures.
