Some special areas on board also require: Heat-resistant cables, chemical-resistant cables, slow-burning cables or explosion-prevention cables.
The figure above is the cross-section example of the control cable type with 5 layers of boc (In order from the inside): Copper core > Fireproof layer > Insulated EPR rubber layer > PVC cover > Mesh cover > PVC cover outer protection.
Types of Marine Electric Cable:
Dynamic cables (for power and lighting systems – Power & Lighting)
250V control cable (using control signal connection)
250V telephone cable (for telephone and device networks – Telephone & Instrument)
In addition, the above cables are also added: Slow fire, Re-fire, Anti-interference …
