The TML 4G2,5 is a submersible cable specifically designed for continuous use in drinking water, making it ideal for connecting electrical equipment such as submersible pump motors. It can also be used in utility water and features a highly chlorine-resistant insulation that remains stable at a temperature of 31 °C and a chlorine concentration of 1.0 mg/L. The cable is designed for moderate mechanical stress and is suitable for use in dry, damp, and wet rooms as well as outdoors. The blue-colored outer sheath made of EPR (Ethylene-Propylene-Rubber) ensures high flexibility and resistance to environmental influences, while the bare fine-stranded copper conductor class 5 provides optimal conductivity and mobility. The core insulation and outer sheath comply with VDE 0507 T. 20 and T. 21 respectively, underscoring the cable’s reliability and safety.

The TML 4G2,5 features a rated voltage of 600/1000 V for protected installation and a test voltage of 2500 V, qualifying it for demanding industrial and technical applications. The maximum allowable tensile stress is 15 N per square millimeter of conductor cross-section, enabling safe installation and routing even under load. The temperature resistance ranges from -25 °C to +80 °C for movable installation and from -40 °C to +80 °C for fixed installation, making the cable suitable for use in climatically challenging environments. The core identification follows VDE 0293-308, ensuring clear identification and safe wiring.

Note (internal)
Inconsistent technical data: Source 3 states a rated voltage of 450 V (U0) and 750 V (U), while Sources 1 and 2 specify 600/1000 V. Additionally, Source 3 mentions a maximum conductor temperature of 90 °C and an allowable ambient temperature range of -40 to +90 °C (both fixed and movable), whereas Sources 1 and 2 indicate -25 to +80 °C (movable) and -40 to +80 °C (fixed). The specifications for sheath material (EPR vs. rubber CR 5GM3) and conductor coating (bare vs. tinned) also vary. These inconsistencies are not reflected in the product description, as the data from Sources 1 and 2 are more consistent and specific, and reference VDE standards. Therefore, data from Source 3 were not adopted to avoid inconsistencies.
