Tomsk Cable Research Institute (JSC NIKI, Tomsk, part of the Cable Alliance Holding, which unites the cable assets of UMMC) received a patent for a power flexible mine cable. The improved design is capable of withstanding a breaking load one and a half times more than analogs.
This type of cable is used to power self-propelled cars, and during its operation the risk of damage is inevitable. The mining enterprises have received a request for design improvements in order to increase the breaking load. The employees of the institute, together with the technologists of Sibkabel JSC, which specializes in mine cables in the structure of the Cable Alliance Holding, found a constructive solution.
“The product provides an additional element - a core twisted from high-strength aramid threads. If earlier the cable withstood a breaking load of less than a ton, now it is up to one and a half tons (in fact, it is able to withstand the weight of a car). At the same time, the service life of the cable has increased by 1.5-2 times, "said Sergei Okunev, head of the scientific and technical department of NIKI Tomsk.
The patented design was developed for about 5 months, at the moment it has been released a pilot batch, which will be transferred to the consumer for testing. After trial operation and a positive conclusion, the products will be introduced into production.
“The production of products for the mining industry is one of the key activities of Sibkabel JSC. When working in hard-to-reach conditions, increased requirements are imposed on the quality and reliability of cable and wire products (PPC). Our technologists, in collaboration with NIKI specialists, are working out all kinds of options for improving the operational characteristics of the gearbox. Thanks to new developments, the plant strengthens cooperation with existing partners and gets expanded opportunities to enter new markets, ”said Alexey Zhuzhin, director of Sibkabel JSC.
