When we install electricity, we often encounter some outdoor installation situations, including outdoor wiring of lighting fixtures and distribution boxes. At this time, what kind of cables and wires should we choose? This article will explain it to you in detail.
Commonly used cables and wires outdoors are mainly divided into the following categories:
Bare wire: wire without insulation layer, mainly used for outdoor overhead use, such as high-voltage transmission lines.
Insulated wire: There is an insulation layer around the conductor to prevent short circuit or leakage when the wire contacts other objects. According to the type of insulation material, it can be divided into many types, such as polyvinyl chloride (PVC), rubber, etc.
Heat-resistant wire: Wire specially designed for high-temperature environment, suitable for high-temperature equipment.
Shielded wire: There is a shielding layer wrapped around the insulation layer to prevent electromagnetic interference.
Power cable: used to transmit and distribute electrical energy, suitable for high-voltage transmission and distribution.
Control cable: used in control systems to transmit control signals.
Communication cable: used to transmit telephone, data and other signals.
RF cable: used for high-frequency signal transmission.
At the same time, these cables also have some common characteristics.,Features:
Bare wire: corrosion-resistant, high-temperature resistant, but easy to short circuit.
Insulated wire: safe and reliable, but the cost is high.
Heat-resistant wire: suitable for high-temperature environment.
Shielded wire: strong anti-interference ability.
Power cable: suitable for high voltage and high current transmission.
Control cable: stable signal transmission.
Communication cable: data signal transmission.
RF cable: high frequency signal transmission, good compatibility.
