Packing

Each single cable length been wound on an iron stand-wooden composite or pure wooden drum.

Standard drum length is 2000m ±2%, or it can be delivered as customer requirement but not longer than 6000m with a tolerance.

Covered by plastic buffer sheet.

Sealed by strong wooden battens.

At least 1m of cable inner end should be reserved for testing.
