Field-Use XTRT Series Special Flexible Power Cable

Overview

XTRT series of special soft power cables are divided into power cable and control power cable, power cable is suitable for power transmission; control power cable is suitable for instrumentation and control of electrical equipment.
The product adopts oil-resistant elastomer material as insulation, special soft elastomer material as sheath, with excellent electrical performance, anti-aging, low temperature resistance (-45 ℃), oil resistance, moisture resistance, mildew shade and acid and alkali erosion and other characteristics. The cable structure is soft and easy to install, and is suitable for energy and information transmission of power and electrical equipment in outdoor environment under mobile occasions.
