60245 IEC 53 Ordinary duty rubber sheathed cord - Taitong Cable

60245 IEC 53 ordinary duty rubber sheathed cord is a 300/500V flexible rubber cable supplied by Taitong Cable, an experienced manufacturer and supplier based in China with more than 25 years of cable production expertise. IEC 53 rubber cable adopts finely stranded Class 5 flexible copper conductors, EPR (Type EI4) rubber insulation for each core, together with a unified rubber (SE3, general-purpose rubber sheath compound, PCP /neoprene) outer sheath. The flexible rubber cable features excellent bending flexibility, single vertical flame retardancy and stable dielectric properties, designed for indoor light‑duty fixed and flexing applications. Structurally equivalent to GB YZ cable and H05RR‑F (EN 50525-2-21), the cable meets IEC 60245‑4 standard, not suitable for heavy‑load, oil‑polluted or long‑term outdoor exposure. Taitong Cable supports international clients, electrical contractors and national project tenders with factory direct pricing, consistent quality and complete after‑sales service.

Construction of 60245 IEC 53 Rubber Cable 

---

Conductor: Class 5 fine stranded annealed copper (tinned optional), IEC 60228

                  plain copper as standard, tinned copper optional for anti-oxidation.

Separator: Optional textile tape

Insulation:  Extruded IE4 (EPR ethylene propylene rubber),good dielectric property.

Core arrangement: Twisted insulated cores, optional filler, IEC standard colour identification

Sheath: Extruded SE3 general rubber compound,flexible and easy to strip without damaging insulated cores.

Number of cores: 2 core, 3 core, 4 core, 5 core

Cross-sections typically from 0.75 mm² to 2.5 mm² (supporting roughly 10A to 20A)

Other sizes of 60245 IEC 53 are available upon request.

Applications of 60245 IEC 53 Ordinary Duty Flexible Rubber Sheathed Cable 

---

This 300/500V ordinary duty rubber sheathed cord is engineered for indoor light‑duty fixed installation and repeated flexing service.

Main Applications of 60245 IEC 53

1, Household and Office Appliances: Power supply cords for light‑duty home electronics, kitchen appliances and movable indoor equipment

2, Handheld Tools and Instruments: Connection cables for small power tools and testing instruments under light mechanical load

3, Fixed Internal Installations: Internal wiring for furniture, decorative cladding, partitions and prefabricated building components

4, Temporary Wiring: Indoor extension cords and temporary site power connections

Environmental Conditions: Suitable for dry, damp and wet indoor locations; limited short‑term outdoor use is permitted.

Operating temperature: -25°C to +60°C for flexing operation, down to -40°C to +60°C for fixed installation.

Important Limitations

60245 IEC 53 rubber cable is not suitable for oil‑contaminated locations, heavy mechanical stress, long‑term outdoor exposure or harsh weather conditions, as it adopts SE3 non‑oil‑resistant rubber sheath. For heavy‑duty or oil‑resistant working conditions, select 60245 IEC 66 or H07RN‑F instead.

Colour identification of 60245 IEC 53 follows IEC 60445 

---

(Green/yellow exclusively for earth conductor)

2-core: Brown, Blue

3-core: Brown, Blue, Green/Yellow (protective earth)

4-core: Brown, Black, Grey, Green/Yellow

5-core: Brown, Black, Grey, Blue, Green/Yellow

Custom core colours and outer sheath colours are available subject to MOQ. The green-yellow core for protective earth conductor shall comply with IEC 60445 and cannot be customized.
