submersible pump cable 100m depth

6 Min Read
TML® submersible pump cable is the professional-grade electrical solution designed specifically for permanent submersion in drinking water systems, deep well applications, underwater pump installations, and saltwater coastal environments. Unlike general-purpose control cables that degrade when exposed to continuous moisture, the TML cable family features tinned copper conductors, AD8 water-resistant rubber insulation, and robust rubber sheathing engineered to maintain electrical integrity even after months or years of 24/7 submersion.

For permanent immersion in water up to a depth of 10 meters, the standard recommendation (according to DIN VDE 0285-525-2-21 / EN 50525-2-21) is the H07RN8-F cable. While the standard H07RN-F is water-resistant (AD7), it is not designed for permanent submersion at depth. The H07RN8-F is specifically engineered with a water-resistant rubber compound that prevents water permeation (swelling) of the insulation, which could lead to electrical breakdown. 对于深度达 10 米的永久性浸水，标准建议（根据 DIN VDE 0285-525-2-21 / EN 50525-2-21）是使用 H07RN8-F 电缆。虽然标准的 H07RN-F 具有防水性（AD7），但它并非设计用于深度的永久浸没。H07RN8-F 专为防止水渗透（膨胀）绝缘层而设计，采用防水橡胶化合物，可防止绝缘层电气击穿。
