Table
Cable Bend Radius by Cable Type
Cable Bend Radius by Cable Type reference with assumptions and boundary notes.
Reference boundary
Bend-radius reference only. It does not set a universal rule, replace cable manufacturer instructions, or approve field bends.
Reference table
Compare common cable-family bend-radius multipliers for preliminary routing conversations.
| Cable family | Reference multiplier | Example at 20 mm OD (mm) | Boundary |
|---|---|---|---|
| Armoured cable | 6x cable OD | 120 | Planning reference only; cable markings and manufacturer instructions govern bends |
| Portable/flexible cable | 6x cable OD | 120 | Planning reference only; cable markings and manufacturer instructions govern bends |
| Large power cable | 8x to 12x cable OD | 160 to 240 | Planning reference only; cable markings and manufacturer instructions govern bends |
| Manufacturer-specific cable | Use product data | product data | Planning reference only; cable markings and manufacturer instructions govern bends |
Use notes
- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
