RFQ: Common Questions and Answers
What makes the КГРЭкППу cable flexible?
The flexible design (гибкий) is achieved through the use of multi-stranded copper conductors and a combination of materials that allow the cable to bend and move without breaking or losing integrity. This flexibility is essential for mobile equipment that constantly changes position.
How does the combined shielding protection enhance the cable's performance?
The combined shielding protection (комбинированная экранная защита), which includes tinned wires and synthetic threads, significantly reduces electromagnetic interference, ensuring stable and reliable power transmission in mining environments where electrical noise can be prevalent.
Why is the polypropylene insulation for auxiliary conductors important?
The polypropylene insulation (изоляция вспомогательных жил из полипропилена) provides an additional layer of protection against electrical faults and enhances the cable's overall durability, especially in environments where mechanical stress is common.
What benefits does the polyurethane sheath offer?
The polyurethane sheath (оболочка из полиуретана) provides excellent resistance to abrasion, chemicals, and environmental factors, ensuring that the cable can withstand the harsh conditions of open-pit mining operations. Its durability extends the cable's service life and reduces the need for frequent replacements.
