Modern power cables such as power cable odm and welding machine cable wire come in many sizes, materials and types, each uniquely suited to its purpose. Large single insulated conductors are sometimes called power cables in the industry.
The cable consists of three main parts: conductor, insulation layer and protective sheath. The composition of a single cable varies from application to application. Structure and materials are determined by three main factors:
Working voltage, determine the thickness of the insulation layer;
Current carrying capacity, determine the cross-section size of the conductor;
Environmental conditions, such as temperature, water, chemical or solar exposure, and mechanical shock, determine the form and composition of the external cable sheath.
All common internal power lines in your home are likely to use dual core and ground cables. As the name implies, this type of cable consists of two core wires, insulated by a PVC outer casing, with a ground core wire between the two.
Cables are classified into the following five types according to their use:
Ribbon cable. It consists of several insulated wires parallel to each other and is used to transmit multiple data simultaneously.
Twisted pair cable.
Fiber optic cable.
The most common sizes for residential work are 14 and 12. Larger appliances, such as electric stoves, electric water heaters, electric clothes dryers and central air conditioners, usually use size 10, 8 or even 6 wires.
