Product Portfolio and Technical Capabilities

Thermo Cables Limited is a specialty cable manufacturing company that is synonymous with quality and satisfying customers’ needs in the most critical areas. Our product range includes – LV power & control, instrumentation, thermocouple, fire resistant, high temperature (PTFE, FEP, PFA, ETFE, ECTFE and SiR), E-beam, elastomeric and other specialty cables.

With the addition of the E-beam facility, our supplies are extended to railways, navy – ships & submarines, offshore, marine, wind mills, solar plants and material handling sectors. The E-beam wire and cables offer superior performance in demanding applications, and in extreme environments.

Manufacturing and Technical Setup

Presently, we have a 3-MeV accelerator and another 2-MeV accelerator is under installation. Our 3-MeV accelerator is equipped with a reflection magnet which collects unused energy and reflects back onto the cable which increases the depth of beam penetration and enables to cross-link cables of large diameters.

Market Footprint

We have made good progress in terms of approvals with Indian railways and Indian navy who are the major consumers of the E-beam cables. We have become an approved supplier after satisfying qualifying requirements with Indian railways in a short period of time as compared to our close competitors. There’s been a surge in our international marine sector business for EBXL cables after obtaining ABS approval and we’ve also got ourselves associated with global wind companies.

At present, we are serving to – railways, shipbuilding, marine, offshore, wind mills, solar plants and material handling industries. Having established ourselves as a prominent player for EBXL cables in the domestic market, we are now looking for more opportunities in the global market with renowned transport companies such as – Siemens, Alstom, Bombardier Inc., etc.

Raw Material and Quality

Using the right compound is essential for E-beam cables and we are proud to have our own compounding facility which ensures quality, shorter lead times and competitive prices. We are making various compounds such as – EPDM/EPR, EVA, CPE, PCP, CSP, SHF2, and LHLS for non-toxic and non-corrosive halogen-free E-beam cables that are used for critical applications in railways, navy, windmills, solar plants etc. While processing these compounds, we consider features such as – tensile strength, elongation, hot set and permanent set, fire properties, halogen content, toxic levels etc., which are very important for the performance of E-beam cables.

Market Potential and Demand Shift

With an estimated potential of Rs. 2,000 cr per year in the domestic market for E-beam wires and cables, we would like to have as much share as possible from this consistently rising demand. We are educating our customers about the advantages of the E-beam cables over conventional cables and going forward, we are confident of the customers demanding E-beam cables for many of their applications.

Advantages Over Conventional Curing Process

The benefits and advantages of E-beam cross-linking are well-established and it is the most important commercial application of radiation technology. The major advantage of the E-beam cables is that they are lightweight with reduced diameters due to thin wall insulation/jacketing with improved service life than the conventional curing process. The E-beam cables are cured at room temperature whereas conventional curing is done at higher temperatures and may deteriorate the thermal properties of the insulation/jacket materials.

Some of the other advantages include – improved service/operating temperature, increase in current carrying capacity, and improved mechanical properties. Moreover, the service-life of the cable is also increased with this process, which is environment-friendly and ensures uniform curing of the cable. Also, the E-beam cables have improved abrasion-resistance; high throughput, improved flame propagation resistance, and reduction of short-circuit conditions.
