Copper cables of the main distribution circuits in a large industrial installation.

This manual provides information on copper-conductor wire and cable, from very low voltages up to 1 kV, that is used in buildings.

Copper Underground Electrical Transmission Systems, deals with the transmission of high-voltage power between electrical generating stations and distribution systems, and for example, between substations.

Copper Medium-Voltage Power Cables, deals with the medium-voltage cables for the main distribution systems, which spread from the substations to the consumers of electrical power.

After the medium-voltage systems, it is necessary to place the power in the hands of the consumers. Included are such items as service entrance cables, the internal building wire circuits to the individual equipment, lighting and appliances, low-voltage circuits for equipment control, door bells, fire and smoke alarms, decorative lighting, and cables for data and communications systems.

Demand for electrical power has grown dramatically, because of its ability to serve in getting work done, in providing living facilities and in being part of travel and recreation. Huge strides have been made in telecommunications. There is now extensive data communication and developments in recent years have incorporated many new features into modern office and commercial buildings. In homes, there are automated mechanical and electrical systems, integrated communications and enhanced electronic security systems. Another major development is Electrical Energy Efficiency, of prime interest in the operation of electrical equipment in the primary and secondary industries, where the use of larger cable sizes, combined with the high conductivity of copper, use less power to get the same amount of work done.

Copper Instrumentation Cables provide information and control for the operator during a processing operation in a steel mill.
