Description

Halogen insulation power cable used on ship

Technical field

This utility model relates to a kind of cable, particularly relates to a kind of Halogen insulation power cable used on ship.

Background technology

Modern ships electrifing degree is more and more higher, and the dependence to power supply is increasingly stronger, and power supply-distribution system becomes One of indispensable important system of modern ships, system not only to ensure not interrupt setting boats and ships are important in the case of severe Standby power supply, maintains higher power supply quality again under conditions of the numerous and diverse change of operating mode.

Utility model content

This utility model provides a kind of simple and compact for structure, good mechanical property, fire resistance to solve problem above Good, the Halogen insulation power cable used on ship of low smoke and zero halogen, length in service life.

The technical solution of the utility model is: described cable includes four insulated wire cores and a fire-retardant inner core, described Insulated wire cores be made up of conductor, insulating barrier, internal shield, inner sheath, described conductor is ferroaluminium conductor, and described is exhausted Edge layer is organosilane crosslinked polyethylene insulation layer, and described internal shield is semiconductive material screen layer, and described inner sheath is poly- Ethylene polypropylene inner sheath, described fire-retardant inner core is arranged on cable center, and four described insulated wire cores are arranged on fire-retardant inner core Periphery, the described common wrapped waterstop of four insulated wire cores constitutes cable core, arranges total screen layer outside described cable core, described Total screen layer is aluminium alloy interlocking screen layer, arranges oversheath outside described total screen layer, and described oversheath is Halogen crosslinking Polyolefin oversheath.

Described waterstop has two-layer.

This utility model is simple and compact for structure, good mechanical property, fire resistance are good, low smoke and zero halogen, service life are long, cable Anti-driving power also have a certain degree of increase, be a kind of function admirable, compact conformation, there is relatively high fire-retardance ability, be suitable for The novel cable that boats and ships use.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, 1 is conductor, and 2 is insulating barrier, and 3 is internal shield, and 4 is inner sheath, and 5 is fire-retardant inner core, and 6 is waterstop, and 7 are Total screen layer, 8 is oversheath.

Detailed description of the invention
