What are multi-core cables?

Multicore Cables

The term "multi-core cables" covers a variety of different cables and wires. These are cables that have at least two separately isolated live souls within the outer insulation. For example, the number of telephone cables can reach 200. One exception is the grounding straps, which may consist of a braid, similar to a strand, but are single-core in the electrical sense. Depending on the application, many cross-sections are used, some cables are provided ready for use with plugs and sockets (pre-assembled).

The insulation protects the inner conductors against contact as well as other external influences and partly has special thermal and chemical properties. A distinction is made between rigid or moving laying in the operating temperature. Silicone insulations offer a much wider temperature range than conventional ones. For a systematic and error-free work, the wire insulations in multi-wire cables are differentiated in color. Within the outer insulation, many cables are located in so-called twisting or twisting. This reduces the mutual interference of electrical conductors.

With the multi-core cables offered in Conrad's shop, you are able to solve any installation task in the industrial, domestic and private sector.

 

Which multi-core cables are available from Conrad?

The multi-core cables offered by Conrad are essentially divided into the following areas of application:

 

Alarm Cables

Alarm, fire alarm cable Alarm, fire alarm cable

With special thermal properties of the insulation, partly in shielded design

AV Cables (By the Metre)

Audio, video cable, unassembled cable

By the meter in packed quantities

Bus Cables

Bus Cables

Among other things, cable with drag chain capability and torsion-resistant

Data Cables

Data Cables

For the safe data transfer even over long distances, some designed for the evaluation of sensor signals, as control and USB lines

Cable for controlling vehicle components, blinds, electric motors, sensors and much more as well as for connecting to batteries

Phone & Telecom Cables

Phone & Telecom Cables

For laying telephone cables, even in the ground or under adverse conditions of industrial use

The very large number of products is due to the fact that some products are available in different lengths, pre-assembled or not pre-assembled or sold by the meter.

Multicore Cables

Within the specified usage categories, it is generally possible to select according to the price range, novelties and offers (with RoHS), customer evaluation, branch availability and by manufacturer (brand). In technical terms, the multi-core cables can be selected according to :

Number of wires: Up to 200.

Cable length: In centimeters, partly by the meter

Cross-sections of the individual wires: In various dimensions

Special features: Chemical, oil and/or UV resistance, suitable for outdoor or earth laying, exceptional temperature resistance, shielding in (special) subcategories

Cable type: Classification usually by systematic designation, for cables such as for loudspeakers or microphones with manufacturer-specific own names.

Multicore Cables

Other special features (not all):

CCA conductor

Abbreviation for Copper Clad Aluminum

Flame-resistant

In the event of a fire, low corrosive gases and smoke develop

Flexible

Combines strands in different wire versions

Shielded

The label "…(St)…" in the cable type means shielding

Halogen-free

The insulation is free of halogens (bromine, iodine, fluorine, chlorine). Avoids toxic and corrosive gases in case of fire

Flat design

Wire routing always side by side with separable bars

Torsion-resistant

Torsion-resistant, for example, when used on moving machine parts. A possible number of torsions for a defined temperature range is assured

Cable type: According to the internationally used abbreviations (letter and number combinations) – often a reference to the application possibilities.

 

About multi-core cables

Multicore Cables

All wires, cables and cables are marked with abbreviations. There are European and national standards. Some examples are:

H as the first letter refers to cables according to the standardized short-term system within Europe

LiY means extra-low voltage stranded wire for fixed wiring, PVC insulation, flame-resistant

FRNC : Flame Retardant Non Corrosive for insulating coats that are flame resistant and do not release corrosive gases in the event of a fire (alternative abbreviation: LSNH)

A-2Y(L)2Y 02X2X0.6 SW is a telephone subscriber cable with PE insulation of the wires and the sheath for laying indoors, outdoors, in soil, in water and in concrete

 

FAQ – Frequently Asked Questions about Multi-Core Cables

What must be observed when using multi-core cables?

  • Cable installation is in the hands of trained specialists, also for laying and repairing in the low-voltage area. The applicable regulations must be observed in order to prevent the danger to persons and objects from electric current.
  • In public places, the laying of cables may be subject to permits.
  • When establishing communication networks, precautions must be taken for data security.
  • Adhere to the specified voltage and current ranges that are intended for the cables. This applies, among other things, to the prescribed temperature ranges.
  • Adhere to minimum allowable bending radius specifications. These radii are quantified differently, depending on the fixed and movable installation.
  • When carrying out repairs, always use cables with the same electrical characteristics and color-identical insulation as a replacement.
  • If necessary, observe separate regulations, e.g. for public buildings, lifts, fire protection equipment and emergency systems. Regular checks are sometimes required by law.
     

How long does a multi-wire cable last?

Cable life is indicated by various manufacturers with 30 to 50 years.

How do defective multi-core cables become noticeable?

  • Clearly visible cable and/or insulation breakage or breakdown, often at entry or exit from housings
  • A complete failure of the power supply or individual components of an installation
  • Current fluctuations when individual wires of cables in the wire structure are interrupted
  • Abnormal heating of the cable
  • Disconnected electrical connections to connected components
