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.
