What is the current carrying capacity of the cables?
There are many different cables and many different installation specifications. For land-based installations there are carrying capacity tables at www.draka.no/Technical information/Technical Manual (Tables)
Which cables can be used in seawater?
TERE 1kV is a special alarmed submarine cable, which is recommended. The EMC-Line (IFSI) 1kV with Cu conductors can be used in shallow waters, if the cable is protected mechanically. Use of PVC-insulated cables is not recommended.
Which cables can be used on a floating pier?
The cables should have cable protection pipes and there should be slack between the floating piers.
Flexible rubber cable H07RN-F is recommended; PVC-insulated cables are not recommended.
What is transposition?
For signal and instrumentation cables, pair or quadruplet structures are frequently used. Pairs or quadruplets that have been twisted together are transposed. Can be measured by number of slag per meter.
Which cables can be used at a fish farming facility?
Predominantly armoured submarine cables should be used, but other PEX-insulated cables, such as EMC-Line and TXOI also withstand submarine installation. It is, however, important to point out that these are not armoured cables and that these withstand considerably less mechanical load. PVC-insulated cables are not recommended. Cables with Al conductors should not be used.
Which cables can be used in explosion zones?
Only screened cables shall be used in hazardous explosion zones.
Current carrying capacity, rubber cables?
See the table on our website under www.draka.no/Technical information/Choose the correct rubber cable.
Highest traction at the installation?
For extraction of cables directly in the conductors, the following limit values must not be exceeded:
For cables with copper conductor: 50 N/mm² conductor area
For cables with aluminium conductor: 25 N/mm² conductor area.
High-voltage cable with hard al conductor: 40 N/mm² conductor area.
Do not include the screen or concentric conductor when calculating the conductor area.
