The main characteristics and selection recommendation of locomotive power cable

Urban rail transit power cable is a “blood vessel”, which undertakes the function of conveying power and transmitting signals, and its variety and quantity are large. The quality of the cable directly affects the stability and safety of rail transit operation. Once the cable fails, it will lead to power interruption or signal transmission interruption and failure, which will have a significant impact on vehicle operation. Therefore, the design and selection of power cable for locomotive power supply system is very important.

Railway locomotive power cable

The cable used on the railway locomotive is required to be low smoke and no (low) halogen, flame retardant, fire resistant, oil resistant, UV resistant, moisture resistant, waterproof, mildew resistant, rat resistant, and termite resistant in the southern region.

Cable products can meet the wear resistance, high temperature resistance, cold resistance, tensile resistance, bending resistance, anti-rat ant, flame retardant, fire resistance, UV resistance, radiation resistance, electromagnetic compatibility and other complex environmental requirements.

Cable features:

1, using copper/tinned copper core conductor, low resistivity, good electrical conductivity, excellent mechanical properties;

2, the use of cross-linked polyolefin/high-energy polymer insulation, and has excellent electrical properties, mechanical and physical properties and excellent waterproof performance;

3, the use of low-smoke halogen-free flame retardant polyolefin material as the outer sheath of the cable, with anti-ultraviolet, flame retardant, non-toxic and low smoke performance.

4, the product environmental safety, high reliability, long service life.

Testeck focuses on cable applications and solutions in the field of rail transit, has 11 years of experience in the field of rail transit, passed the CRCC certification, has the independent intellectual property rights of key technologies, is the earliest domestic rail transit cable production enterprises and passed the loading and operation assessment, the production of locomotive power cables widely praised.

Testeck locomotive power cable

The Tester Rail locomotive power cable (EN50382) maintains its power transmission function under high temperature conditions and has special fire protection properties, contributing to the safety of transport.

Cables with or without sheathed shall be insulated and sheathed with halogen-free silicone rubber materials. In the event of a fire, it can prevent the spread of flames, reduce the emission of toxic gases and smoke, reduce the loss of visibility, and enable personnel to quickly evacuate to prevent the fire from causing damage to the railway system.

Tester cable characteristics

1, the cable AC rated voltage is 1.8/3kv, 3.6/6kv.

2, the working temperature of the cable is -50℃ -120 ℃ or 150℃.

3, the allowable bending radius of the cable: 6 times the outer diameter of the cable.

4, fire rating: meet EN45545-2 R15/R16 HL3.

5, toxicity index: equivalent to the European standard toxicity index is not more than 3, equivalent to the iron standard toxicity index is not more than 5.

6, the cable is resistant to solvent, acid and alkaline energy, can be used in the occasions polluted by mineral oil and fuel oil.

Tester Cable has been deeply engaged in the field of rail transit for 11 years, and its products cover EN50264 series, EN50306 series, EN50382 series, thinned cables, data cables, sensor cables, jumper cables, high temperature resistant cables, high cold cables, etc.

It is suitable for EMU, high-speed rail, subway, urban rail, ordinary locomotive and other models, and is committed to promoting the continuous innovation of connection transmission technology and products in the field of rail transit.

With the spirit of craftsmanship of excellence, Testeck Cable continues to create professional and reliable cables and high-quality sustainable solutions, and has won the support and trust of many customers.
