Rubber insulated and sheathed rubber flexible cable YC/YZ/YCW

YC / YZ / YCW Rubber Flexible Cable — Heavy-Duty General-Purpose Rubber Cord

YC, YZ, and YCW are Chinese standard (GB/T 5013) general-purpose rubber flexible cables for a wide range of portable power applications. YZ is the light-to-medium duty variant; YC is the heavy-duty version with a thicker sheath; YCW adds weather and oil resistance for outdoor and industrial use. All feature fine-wire stranded copper conductors with rubber insulation and sheathing.

Available in 2 to 5 cores and conductor sizes from 0.75 mm² to 95 mm², rated at 300/500V (YZ) or 450/750V (YC, YCW).

Designation Comparison

• Temperature range ‑40°C to +65°C (YC/YZ); ‑40°C to +75°C (YCW)
• 2 to 5 cores; 0.75 mm² to 95 mm²
• Manufactured to GB/T 5013, performance equivalent to IEC 60245

Typical Applications

• Portable electric tools — drills, grinders, welders
• Mobile cranes, excavators, and construction equipment
• Agricultural machinery and irrigation pumps

• Mining equipment and tunnel boring machinery
• Industrial machinery requiring flexible power connections

Selection Guide

Choosing Between YZ, YC, and YCW

Use YZ for light tools and small appliances (up to 300/500V). Specify YC for heavy industrial equipment requiring 450/750V and greater mechanical protection. Choose YCW when the cable will be exposed to outdoor weather, rain, or oil splash. YC is functionally equivalent to H07RN-F; YZ to H05RN-F.
