ZTT Marine Medium Voltage Cable
The marine medium voltage cable is widely used for MODUs (Mobile Offshore Drilling Units), commercial ships, and floating or fixed offshore facilities. The cable utilizes braided shields and versatile stranded conductors. It makes the marine MV cable very suitable for an operation that involves high vibration and repeated flexing. Moreover, the flexibility of marine MV cables enables one-end termination and multiple coiling of module offshore platforms.
ZTT is a leading marine medium voltage cable manufacturer in China that obtained RS, LR, ABS, DNV-GL, RINA, BV, and CCS type approval certificates. Our team aims to produce low smoke, flame retardant, fire-resistant, and halogen-free marine MV cable to protect the health and safety of every shipboard worker. ZTT also supports custom services to meet your different needs.
ZTT medium voltage marine power cable is widely used on marine ship boards. It features flame retardant, low smoke, zero halogen and fire resistant.
The single-core marine medium voltage cable is used for electrical power system. It is marine type approved by main classification societies.
Our 3 cores medium voltage marine cable is in compliance with IEC 60092-354 standard and ABS, BV, LR, RINA, RMRS, and DNV-GL type approved.

Different Insulation Materials for Marine MV Cable
- Improve the breakdown (dielectric) strength, reduce electrical losses, and hinder the growth of electrical trees.
- XLPE compounds are rated 90ºC for normal operation.
- Withstand degradation that would cause a failure of the insulation.
- Retain break-down (dielectric) strength in service over the life of the installation, give proper storage and handling of the cable prior to installation of the cable.
- Reliability, superior flexibility, and strong performance in wet application.
- Rated 105ºC for normal operation.
