6~20 kV 1Core RHEYFIRM (SI) NTMCGCWOEUS Cable 1×95/16 Manufacturer
6/10 kV 12/20 kV (SI) NTMCGCWOEUS Cable 1×95/16 is flexible high voltage cable for used normally in short lengths, as a reliable power connection for various mobile heavy machinery, mining gear and construction equipment. It is the preferred choice for worksites where cables need to move constantly and endure severe operating conditions e.g. between short-circuitbreaker and mobile transformer.
(SI) NTMCGCWOEUS Cable Feature
- Strong protection against abrasion,
- Chemical oils and bad weather.
- High flexibility and anti-stretch properties let it adapt to frequent movement and complex on-site stress.
(SI) NTMCGCWOEUS Cable Description
NTMCGCWOEUS stands out as a heavy-duty rubber cable tailored for rigorous industrial and mining scenarios. Crafted with premium rubber insulation and sheathing, it boasts outstanding resistance against wear, oil, dampness and all kinds of outdoor elements. Thanks to its superior flexibility and tensile capacity, the cable copes easily with repeated bending, pulling and mechanical shocks. It maintains steady electrical performance even under prolonged heavy loads.
NTMCGCWOEU is ideal for fixed or low-frequency moving equipment in power distribution rooms and conventional workshops. NTMCGCWOEUS, however, is tailored for reel systems, mobile mining machinery and crane facilities that require round-the-clock movement. To sum up, the standard NTMCGCWOEU focuses on stable basic performance, while NTMCGCWOEUS is optimized for extreme mechanical stress and long-duration dynamic operation.

Differences between NTMCGCWOEUS and NTMCGCWOEU
NTMCGCWOEUS and NTMCGCWOEU are both VDE-standard single-core medium voltage flexible cables, widely adopted for industrial and mining power connections. Despite shared basic electrical specifications, they differ greatly in internal structure, mechanical performance and applicable working scenarios, mainly reflected in the extra design of NTMCGCWOEUS marked by the suffix “S”.
In contrast, NTMCGCWOEUS is an upgraded reinforced version. It adds professional anti-twist and tensile braided layers inside, paired with high-strength composite inner sheath and enhanced PUR outer jacket. These upgrades dramatically improve tensile strength, torsion resistance and wear resistance. It can withstand continuous rolling, frequent bending and heavy mechanical impact, even in rugged sites with sharp ground and intense friction.
