Cables and wires are used for electrical conduction and transmission in the household as well as industrial applications. These wires come in different size, shape, and type and are used for multiple different industries. The difference of the cable type depends upon the temperature level which it can bear, its insulation properties and resistance to other chemicals and corrosive materials.
These cables must be chosen for your application based on the following features —
- Capacity for current carrying and voltage drop
There are several cables and conductor sizes according to the Wiring Rules such as AS/NZS 3000 for the purpose of the wiring of lighting circuits and socket outlets in residential and industrial buildings.
For several other types of usage, you must choose cables such as:
- The cable you buy must have the capability of carrying maximum continuous circuit load, with proper details of the insulating material and installation conditions.
- The voltage drop of the cable in accordance with the consumer’s terminals should not exceed 5% of the voltage of the nominal system at any time of the installation process. If you have a large installation which has critical current ratings one must pay attention to the AS/NZS 3008.1.1:2009.
Installation conditions for the orange circular cable —
The orange circular cables are used widely for underground, aerial as well as submarine installations. They are also used in racks, conduit or trays in the air. While custom construction of the orange circular cable you must choose following options —
- If you require resistance to marine borer or termite then you must choose nylon, brass or copper sheathed cables
- If you are looking for resistance to mechanical damage then try for steel wire armoured cable.
- If you are looking for cables with good fire performance then opt for low smoke halogen free cables.
