Maximum pulling tension must not exceed 50 N/mm2 on the conductor.
Installation temperature must be above 0 degrees Celsius.

Duct Installation:
- Clean and inspect all ducts before pulling
- Apply cable lubricant compatible with the outer sheath material
- Use a cable winch with tension monitoring
- Install at a steady rate of 5-10 m/min

Direct Burial:
- Trench depth minimum 800 mm for urban, 1200 mm for rural
- Sand bedding layer of 100 mm below and above cable
