Abstract
The invention relates to a monitoring and controlling cable for an intrinsically safe anti-explosion instrument of a ship. At least two pairs of stranded wires are stranded to form the cable; the wires are externally provided with split-phase composite shielding layers; the cores of the cables are externally provided with a flame-retardant cable forming wrapping layer, a high flame retardant oxygen isolating layer, an inner lining layer, an overall woven armored layer and an outer protecting layer in sequence; and high-temperature resistant and high fire retardant material used as filling material is filled in gaps of the cores of the cable. The cable disclosed by the invention has good electrical properties and excellent electromagnetic interference resisting capacity and is suitable for a large ship, a giant ocean-going ship and a ship communication and centralized-control signal instrument with high technological content of equipment automation to sail in harsh conditions with temperature, smoke, humidity, radiation, combustion, explosion and electromagnetic interferences.
Description
Technical field
The present invention relates to a kind of naval vessel intrinsic safe explosion-proof instrument and use measurement and control cable, belong to the cable technology field.
Background technology
The fast development of the industry of water transportation both at home and abroad is shipbuilding industry and the manufacturing opportunity that provides good of accelerating development of the various ships of war.China is the naval equipment backward situation for a change; Strengthened in recent years making the dynamics of various Military Warship investments; Building the powerful naval that adapts to marine modernized war needs,, improving electric automatization measurement and control signal laser propagation effect in order to improve the equipment of ocean palace and Military Warship modernization electric equipment; Give full play to the operational efficiency on naval vessel; The automatical measure and control system of modernization naval vessel electrical equipment needs the extraordinary measurement and control signal transmission cables of supporting many performances more and more urgent, especially in the ocean, navigates by water the special cable of instrument and meter for automation equipment for solving the naval vessel, and demand is increasing.
Summary of the invention
The present invention's design often forms whirlpool because of occurring high-intensity magnetic field in the ocean to the naval vessel in ocean navigation; Have a strong impact on the interference of the navigation automation equipment signal transmission of seagoing vessel and Military Warship; Overcome common signal cable performance peculiar to vessel and can not satisfy the drawback of the special supporting requirements of naval vessel TT&C system signal transmission line far away, a kind ofly have multiple performance naval vessel intrinsic safe explosion-proof instrument such as anti-forceful electric power magnetic and strong electrostatic interference, retaining are damp, corrosion-resistant, weather and use measurement and control cable and researched and developed.
The present invention realizes that through following technical scheme by two pair twist zygonema strand strandings, its center line externally is provided with the phase-splitting composite shielding layer at least; Cable core is set as cable lapping layer, high flame retardant oxygen barrier layer, inner covering, total shield layer, outer jacket outward successively; High temperature resistant, high flame retardant material is set as inserts in the space between the cable core.
The conductor of said twisted wire pair is regular stranded the forming of high-quality copper free wire or high-quality tinned copper wire, and conductor is provided with low smoke and zero halogen environmental protection cross-linking radiation polyolefin insulation layer outward.
Described phase-splitting composite shielding layer adopt the plastic-aluminum band wrapped+tinned copper wire braid shielded structure forms.
Described stranding lapping layer adopts fire prevention high flame retardant glass fibre belt.
Described high temperature resistant, high flame retardant inserts employing aramid fiber.
Described total shield layer adopts the tinned copper wire braiding.
Described inner covering and outer jacket all adopt low smoke and zero halogen environmental protection cross-linking radiation polyolefine material.
The present invention is rational in infrastructure simple, manufactures easily, and cost is low, cable smooth in appearance rounding, and serviceability is good.Selecting for use and the setting of composite shielding new technology of new material; Guarantee that cable has multiple property; Under the situation that can make the measurement and control signal transmission line of automated system of naval vessel configuration big, multicomponent salt air corrosion, air humidity is big in strong jamming, heavy load, the temperature difference, measurement and control signal transmission performance reliably.
