Orange circular cable is the most commonly used type of power cable in Australia, and even now many people refer to cables as XLPE power cables. As the backbone cable in power transmission, the orange circular power cable plays an important role in power transmission, such as the arterial vessels in human blood vessels or the trunk of a tree. Orange circular is commonly found in underground passages (manhole covers) or buried underground in cities. Construction teams often cut off power cables during construction, resulting in widespread power outages, known as power cables.
Orange circular cable product classification: ordinary cable, flame-retardant cable, fire-resistant cable, low smoke and halogen-free cable.
product mix
The components of an orange circular cable from the inside out are a conductor, a polyethylene insulator, a filler, and a polyvinyl chloride outer sheath.
Conductors are mostly copper core orange circular cables, which are the most widely used conductor materials on the market. Aluminum conductor cables are less commonly used due to poor conductivity and lack of standards; The filling material is mostly made of materials such as nylon, which plays a role in maintaining the core of the cable and is equivalent to putting a "piece of clothing" on the cable core; If it is an armored power cable, a layer of steel tape armor will be added between the filler and the sheath, with the intention of burying the cable underground to provide pressure resistance. The steel tape armor cable model is STA cable or SWA cable
Specification and model
XLPE cable can be a single cable or a cable composed of multiple conductors. Its core count includes single core, 2-core, 3-core, 4-core, 5-core, 2+E core, 3+E core, 3+2 core, 4+E core, etc. Among them, 3+1 core, 3+2 core, and 4+1 core are composed of two conductors with different effects, one called phase wire and the other called ground wire, which are specifically used for grounding. The commonly used specifications include 1mm ², 1.5mm ², 2.5mm ², 4mm ², 6mm ², 10mm ², 16mm ², 25mm ², 35mm ², 50mm ², 70mm ², 95mm ², 120mm ², 150mm ², 185mm ², 240mm ², 300mm ² orange circular cable, etc. For example, a 4 core and earth orange circular cable consists of 4 main wires and 1 ground wire, a 6mm 2 core and earth orange circular cable consists of 2 6mm ² wires and 1 ground wire, a 16mm 2c e orange circular cable consists of 2 6mm ² wires, and a 25mm orange circular cable is a single cable. 25mm ²
Scope of application
Orange circular cable is suitable for power distribution engineering cables, power transmission engineering wires and cables, electromechanical and hydropower installation engineering cables, power transmission cables, power supply installation system control systems, etc.
The additional UO/U for power frequency is 0.6/1KV.
The cable conductor is allowed to operate at a maximum temperature of 90 ℃ for a long time.
During a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor shall not exceed 250 ℃.
The ambient temperature during cable laying should not be lower than 0 ℃.
Cable bending radius: not less than 15 times the outer diameter of the cable.
