H05V-U, H05V-R, H05V-K Single Core Building Wire

H05V-U, H05V-R, H05V-K single core building wire

 working on control cabinet wiring, internal appliance connections, or protective conduit installations, the H05V family of single-core PVC cables is likely the solution. While all three cables share a standard voltage rating of 300/500V and a thermoplastic PVC insulation, their key distinction lies in their conductor construction. Choosing the right one depends entirely on whether your application requires rigid stability or high flexibility.

Standards:

DIN VDE 0281-3, BS 6004, EN50525-2-314

Construction:

Conductor

Class 1 solid copper annealed conductor for H05V-U;

Cass 2 stranded rigid annealed copper conductor for H05V-R;

Class 5 stranded flexible annealed copper conductor for H05V-K;

The conductors shall comply with the requirements given in IEC 60228.

Insulation

PVC compound type TI 1

Color of insulation: green/yellow, blue, black, brown or as customer required.

Characteristics:

Rated voltages U0/U: 300/500V.

Note:

U0: Rated power-frequency voltage between conductor and earth or armour, metal sheath or screen for which the cable is suitable.

U: Rated power-frequency voltage between phase conductors for which the cable is suitable.

Maximum conductor operating temperature: +70℃

Maximum short circuit conductor temperature: +160℃

Test voltage: 2000V

Application:

H05V-U,the rigid solid conductor, The "U" stands for "solid" conductor. This cable features a single, solid copper wire.

Ideal for fixed installations where the cable will not move after installation. It is the standard choice for wiring inside walls (conduits) and for general purpose internal wiring of distribution boards.

H05V-R, the stranded medium-flex conductor, The "R" stands for "stranded" conductor. It consists of several medium-sized copper wires twisted together.

Widely used in control cabinets and switchboards. It is preferred when the wire needs to be bent during installation but will remain static during operation.

H05V-K, the fine-wire high-flex conductor. The "K" stands for "flexible" (fine-stranded) conductor. It is made up of many very fine copper wires.

Perfect for applications requiring frequent movement or installation in tight spaces. It is commonly used for wiring of electronic equipment, household appliances, and lighting fixtures where wires need to be maneuvered into compact areas.

The core difference is flexibility: H05V-U is rigid, H05V-R is semi-rigid, and H05V-K is highly flexible. All operate at 300/500V, but the conductor type dictates the application—use U for static walls, R for control panels, and K for appliances and tight bends.
