Norbert Kordes H05V-U0,75WS-R100 H05V-U 0.75 mm² white 100 m-reel PVC-insulated single-core cable content_copy

The H05V-U 0.75 WS is a PVC-insulated wiring cable from manufacturer Norbert Kordes, designed for internal wiring of devices as well as for protected installations in and on luminaires, in conduits, on and under plaster. The cable is specifically intended for use in doorbell and signaling systems, with application restricted to these systems. The cable consists of a bare, single-strand copper conductor, which is sheathed with PVC insulation according to VDE 0207. The sheath color complies with the requirements of standard VDE 0293-308, with the color being white, corresponding to RAL 1013.

Applications
The cable is intended for use indoors, particularly in electrical devices, lighting systems, and signaling systems. It is suitable for installations in conduits, in pipes, on and under plaster, with installation under plaster only permitted in protected areas. Use is restricted to systems that do not require higher electrical loads, such as doorbell systems or simple signal transmissions. The cable is not intended for outdoor use or in damp environments, as no specific protection ratings such as IP rating are specified.

Functions and Equipment in Detail
The cable features a bare, single-strand copper conductor, ensuring stable electrical conduction. The PVC insulation according to VDE 0207 provides sufficient electrical insulation and mechanical stability. The white sheath color complies with standard VDE 0293-308 and is thus standardized for use in electrical installations. The cable is rigid, meaning it is not suitable for frequent bending or movement, but intended for fixed installations in devices or systems.

Technology Explained Simply
The rated voltage is 300/500 V, meaning the cable is designed for voltages up to 500 V in phase-to-conductor connections and up to 300 V in phase-to-neutral connections. The test voltage of 2000 V serves for safety testing and ensures that the insulation does not break down under increased voltage. The maximum operating temperature is +70 °C, and during installation, the cable must withstand temperatures from +5 °C to +70 °C. After installation, the ambient temperature can range from -30 °C to +70 °C without damaging the cable. The minimum bending radius is 15 times the cable diameter, which must be considered during installation to avoid cracks or damage to the insulation. Flame retardancy according to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), means that the cable must not burn off during a flame application test and must not continue burning after removal of the ignition source.

Compatibility and Accessories
The cable is intended for use in doorbell and signaling systems, with compatibility provided for standard installation techniques in electrical installations. Installation in conduits, pipes, on and under plaster is permitted, with installation under plaster only allowed in protected areas. The cable is not intended for use in damp or wet environments, as no specific protection ratings such as IP rating are specified. Use in outdoor installations is not intended.

Installation and Mounting
Installation of the cable requires adherence to the minimum bending radius of 15 times the cable diameter to avoid damaging the insulation. Installation takes place in protected areas, for example in conduits, pipes, on and under plaster. The cable is designed for fixed installations and is not suitable for movable applications. Temperature conditions during installation (from +5 °C to +70 °C) and after installation (from -30 °C to +70 °C) must be observed to ensure functionality and service life of the cable.

Operational Advantages
The cable provides reliable electrical conduction with sufficient insulation and flame retardancy. The use of PVC insulation according to VDE 0207 ensures high mechanical stability and electrical safety. The standardized white sheath color according to VDE 0293-308 facilitates identification and integration into electrical installations. The cable is optimized for use in doorbell and signaling systems, with electrical and mechanical properties sufficient for this application. Flame retardancy according to VDE 0472 Part 804, Test Method B, increases operational safety, particularly in enclosed spaces or within devices.
