Tunnel Cable with Super Environmental Adaptability
Hengxun tunnel cable is specially designed for tunnel engineering. We have multiple series of tunnel cables suitable for your different projects. It uses high-quality pure copper as the conductor and is specially twisted. The sheath uses EPDM and is filled with water-blocking glue and non-woven fabric as a water-blocking layer, so that our tunnel cable can adapt to a variety of environments.


Tunnel Cable That Is Easy To Install
Hengxun tunnel cable is 30% lighter than traditional PVC cable and can maintain high flexibility even in an environment of -20 degrees, making your installation more convenient. In addition, because the sheath is made of highly wear-resistant rubber material, the service life of the tunnel cable can be extended to a greater extent, saving your costs.
It is usually caused by multiple composite stresses of bending, torsion and vibration. It is recommended to optimize the wiring path, install anti-torsion rings and design the conductor twisting structure.
It is recommended to use multi-core cables and install shielding structures to prevent electromagnetic interference.
Of course, we can provide customization for you. We can add intelligent monitoring equipment such as optical fiber temperature measurement, online partial discharge detection, and mechanical stress sensors to the tunnel cable.
