What Types Of Cables And Lines Are There?

Power cables for cable protector outdoor that are often used in installations are the NYM-J cables. These are installation cables, the copper lines of which are sheathed with PVC. These 3 to 5-core are laid both surface-mounted and flush-mounted and only require small mortise slots for the latter laying variant.

Anyone who needs an installation cable needs to know which conductor is required for the planned installation. Each wire is insulated in a specific color; its conductor is made of copper and must have a cross-section corresponding to the load. For example, if the installation involves sockets or lighting with an average load, a conductor cross-section of 1.5 mm² is usually sufficient.

However, if a tumble dryer or dishwasher is attached to the socket, the cross-section must be 2.5 mm². In the hobby workshop or at the electric stove, a conductor cross-section of 4 mm² is recommended. Flat cables (NYI-FJ) are straightforward to lay; these flat cables can be attached with unique nails, but only in dry rooms without special protection.

The cable types NYY / NYCWY can be laid as underground cables or power cables in outdoor and indoor areas and water or in concrete following VDE 0298 Part 1. Both types of cables differ in structure.

Cables And Their Designs

JYSTY telecommunication cables/lines are installation cables for telecommunication purposes intended for fixed indoor installation under DIN VDE 0815. The designation A-2Y indicates the suitability for laying according to VDE 0816 as an outdoor cable or underground cable.

YSLY control cables are made based on DIN VDE 0281 and have a largely oil-resistant PVC jacket, the conductor of which is made of bare, fine-stranded copper. They are suitable for dry and damp rooms but not for lying outdoors. YSLY control lines are required for signal and impulse lines and control and regulation technology for monitoring and controlling production lines and production systems.

During installation, power cables are often laid under plaster in flexible pipes (cable ducts) because they can withstand light mechanical loads and heat excellently. However, pulling in subsequent conductors is difficult due to the grooved inner walls.
