The armored cable for marine data communication effectively improves the flexibility, the bending resistance, the flame retardation and the collision resistance.
Description
Technical field
The utility model relates to a kind of seven class cables, relates in particular to a kind of armored cable for boats and ships data communication.
Background technology
The sheath of cable: common maritime affairs adopt conventional PVC(polyvinyl chloride with data cable) or PE(polyethylene) sheath.Due to conventionally on maritime affairs ship; it is larger that hull is affected by external environment and ocean climate; particularly can be regular run under the mal-conditions such as rolling, trim and temperature acute variation, salinity, solar radiation; this protective layer is not only because the impact of environment for use causes its useful life very short; and due to regular rolling, trim; cause anti-external force damage ability to decline, cannot guarantee the accuracy of transfer of data.
The screen of cable: the unshielded layer of the transmission unit of common maritime affairs data cable peculiar to vessel (unit group), can not be applicable to the occasion that jamming performance is had relatively high expectations.
Due to the said structure limitation of cable, adding upper hull, affected by external environment and ocean climate larger, and narrow space in boats and ships in addition, and various kinds of equipment is intensive, various cable boundlings lay generation galvanomagnetic effect severe jamming the stable transfer of signal in conductor.And maritime affairs ship is when maintenance, recovery cable, be easy to affect because force-extension is crooked its serviceability.

Polytetrafluoroethylene outer jacket is coated on described polyvinyl chloride sheath outer surface;
Between described polyvinyl chloride sheath and polytetrafluoroethylene outer jacket, be provided with the armour being comprised of some zinc-coated wires, described some zinc-coated wires are placed side by side.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, described polyvinyl chloride sheath and polytetrafluoroethylene outer jacket Thickness Ratio are 1:0.5 ~ 0.8.
2. in such scheme, at least 8 of the numbers of described zinc-coated wire.
3. in such scheme, described zinc-coated wire diameter is 0.85 ~ 1mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model is for the armored cable of boats and ships data communication, between its polyvinyl chloride sheath and polytetrafluoroethylene outer jacket, be provided with tincopper fuse wire braided armor, effectively eliminated the electromagnetic induction of digital cable self, reduced the electromagnetic interference of cable around, also improved the impact of cable opposing due to mal-conditions such as temperature acute variation, salinity, solar radiations, when guaranteeing the stable transmission performance of cable, extended the life-span that cable is used, reduce maintenance and the maintenance frequency of warship with data cable, there is promotion prospect widely;
2. the utility model is for the armored cable of boats and ships data communication, its restrictive coating is comprised of polyvinyl chloride sheath and the polytetrafluoroethylene outer jacket that is positioned at its outer surface, and be provided with the armour being formed by some zinc-coated wires between polyvinyl chloride sheath and polytetrafluoroethylene outer jacket, there is very large tensile strength, improve the useful life of cable.
