Description

Power cables provide the optimum power supply, while control cables, on the other hand, transmit signals for controlling devices and machines.

A power cable
- supplies devices, machines and plants with energy,
- serves to connect the power supply in buildings,
- distributes energy, e.g. in power stations and converter stations.

A control cable
- transmits control signals within a control circuit and
- controls machine components with these control signals.

Properties

A power cable has at least 1 core and a maximum of 5 cores. A variant with more than 2 cores usually consists of a neutral conductor, a protective conductor and one to three current-carrying outer conductors (phases, L1-L3), depending on the single-phase or three-phase alternating current.

The conductor cross-section is generally ≥ 0.5 mm², the individual cores are colour-coded according to VDE 0293-308/HD 308 (core identification code for colour-coded low-voltage cables and wires). LAPP offers power cables for the low-voltage range up to 1 kV and for the medium-voltage range up to 30 kV.

Control cables are used to establish wiring within and across machines between electrical devices, machines, switchboards, sensors and actuators.

The control cables transmit simple signals used to control machines and their components. The signal receivers execute an action based on the control signals.

A control cable can contain 2 to typically 25 or, in rare cases, up to 100 numbered cores. The conductor cross-section is usually between 0.5 mm² and 2.5 mm², but can also be up to 35 mm² depending on the application. Control cables should be flexible and space-saving and have the smallest possible bending radii.

Applications

In this product segment, LAPP offers you a variety of cables that can be used to cover all applications. Browse through the product range: from simple, universally usable single core cables to multi-core cables for specific purposes such as robot or cable chain applications, or even solar and wind power.
