COMPOSITE SIGNAL CABLES

COMPOSITE SIGNAL CABLES

For environments with high temperatures, high pressure and/or high voltage, we offer composite hybrid structures for data signal transfer. Depending on the application and need for control signals and/or other data transfer, the cable can be furnished with a varying configuration of optical and copper lines. Despite their multi-material composition, these new hybrid cables are extremely light, compared to armoured cables, for example. The product is intended for permanent installation, such as cabling buildings and tunnels.

The cables are produced according to customer specifications by our partner in Germany. On request, we can carry out projects from prototyping to large volume production of kilometres per year. With Refitech, you can count on tailor-made solutions based on your needs.

MULTI-LAYER BASALT CABLE

The multi-layer basalt cable is a new type of composite core. It is made up of high-quality basalt fibre, a thin-walled stainless steel covering of exceptional strength and a communication cable (an optical fibre, coax or copper wire), all combined in a casing of polyamide, polyethylene or high-density polyethylene. This composite cable core has excellent properties:

  • Light-weight
  • Exceptional strength
  • Resistance to high temperatures
  • Low signal loss and low cable sag

A new high-tech material

The cable is based on a new, high-tech material: the mineral fibres found in basalt, an alkaline, volcanic rock. The material was originally used for the thermal insulation of nuclear reactors and is now being further developed as a material mixture that can prevent practically any cable breakage. Frequent repairs due to a cable break are now a thing of the past. Because of this material’s unique properties, it is practically indestructible. It has a very high crack resistance and retains its functionality at very high temperatures.

Basalt fibre properties

  • Operating temperature: -30 °C to +70 °C
  • Maximum temperature: +80 °C
  • Melting temperature: 1.500 °C
  • Weight: around 31 kg/km
  • Resistant to rodents
  • Resistant to chemicals
  • Natural product
  • Good resistance to bending
  • High tensile strength of up to 29 kN
  • Can also be used as a pushrod
  • Optional coating with polyamide, polyethylene or high-density polyethylene
  • Breaking load of up to 12 kN
  • Fire-resistant
  • Multilayer-Basalt-Tube

HYBRID CABLE WITH BASALT AND GLASS | FOR RELIABLE DATA TRANSFER

On top of producing and processing fibre composite components and modules, this medium-sized family business has now expanded its portfolio by producing sliding cables and hybrid cables. These cables are based on high-strength and light-weight composite material. Additionally, all the elements for data transfer are protected by thin but stable basalt or fiberglass rods. This makes the cables extremely robust and flexible, with a high restoring force and resistance to enormous mechanical forces.

Hybrid cables – light, individually adjustable and ‘HD-ready’

Despite their good shear stability, hybrid cables are relatively light and flexible. The hybrid cable is HD-ready and definitely suitable for high-resolution video data transmission.

Basalt – originally used to insulate nuclear reactors

Basalt is a common volcanic rock that is known for its resistance to wear and pressure. Because of its properties, this material was first used as insulation material for nuclear reactors. Now it is also applied to these composite cables. Cable breakages or other forms of damage are virtually non-existent thanks to this mix of materials.

Properties of composite cables

The exact technical specifications are customer-specific and depend on the cable’s composition. We are happy to advise you on your specific application. Below you can find an overview of essential properties:

  • Operating temperature of -30°C to +100°C
  • High strength
  • Light-weight
  • Very good restoring force
  • Extremely small bending radius is possible
  • High flexibility and elasticity
  • Cable composition according to customer requirements
  • Developed and produced in Germany by our partner CG Tec.
