Abstract

The utility model provides an environmental-protective fire-proof nanometer electric wire and cable special for a ship, comprising from interior to exterior three single cables, a flame retardant inner protective cover, an armouring and a flame resistant outer protective cover one after another . The single cable comprises from interior to exterior a conductor, a nanometer fire-proof insulation layer, an isolation layer and a flame resistant insulation layer one after another. The utility model alters the structure of the traditional electric wire and cable special for a ship and has the advantages of low smoke, no toxicity, no halogen, flame resistance, ageing resistance, waterproof performance, moistureproof performance, internal heat resistance, open flame resistance and environment protection. The environmental-protective fire-proof nanometer electric wire and cable special for a ship is a new product instead of traditional products and is suitable for the connecting lines of the electric energy communication, illumination and the control system used by various ship vessels, ships, oil platforms and other waterborne buildings.

Description

Nano environmental protection fire prevention boats and ships special wire cable

Technical field

The utility model relates to a kind of fire prevention boats and ships special wire cable, belongs to technical field of electric wires and cables.

Background technology

Existing boats and ships special wire cable is to adopt common DIN standard production to make, and its structure is: coat heat-resisting 70 ℃ polyvinyl chloride insulation layer outside copper conductor.Find in the practice that this low tension wire cable is all thermo-labile, and is not fire-resistant, more can not prevent fires; The conductor overload current is easy to puncture insulating barrier, causes short circuit, initiation fire; In naked light, the insulating barrier that can ignite very soon causes the electricity fire combustion-supporting, enlarges the condition of a disaster.

Summary of the invention

The purpose of this utility model is that to overcome above-mentioned technology not enough and the nano environmental protection fire prevention boats and ships special wire cable of a kind of both Nai Neire, anti-naked light and environmental protection is provided, and its production cost is low, and processing technology is simple.

For achieving the above object, the utility model provides following technical scheme: design a kind of nano environmental protection fire prevention boats and ships special wire cable, it comprises from inside to outside successively: 3 unit cables, fire-retardant inner sheath, armouring and fire-retardant oversheaths; Described unit cable comprises from inside to outside successively: conductor, nanometer fireproof insulating barrier, separator and flame retardant insulation.

In the such scheme, described nanometer fireproof insulating barrier is extruded and is coated on the described conductor, one-shot forming.

Nano environmental protection fire prevention boats and ships special wire cable of the present utility model, owing to increased the nanometer fireproof insulating barrier, and make original insulating barrier into low smoke and zero halogen, difficult combustion nonflame material, fundamentally changed the internal structure of boats and ships special wire cables, can be from the generation of control circuit fire on the source.Its characteristic is: working temperature is increased to 340 ℃ by 70 ℃; 2.5 times of current overloads, conductor temperature to 340 ℃ sustainable power supply 2 hours, not short circuit does not cause the electricity fire.Under the ablation of 800-1200 ℃ of naked light, electric wire can not ignite in 1.5 hours that electricity fights can continued power.In the naked light ablation process, the not only difficult combustion nonflame of insulating barrier, and no longer discharge suffocative toxic gas; Nanometer fireproof insulating barrier does not wherein not only fire, and can at high temperature play insulating effect, and can guarantee indeformablely in 1200 ℃, meets GB and IEC relevant criterion fully.This low-voltage cable has low cigarette, nontoxic, Halogen, fire-retardant, waterproof, protection against the tide, aging-resistant characteristic, and is grease proofing, anticorrosion, and antiacid alkali is more than three times of traditional electric wire useful life.Main performance is: rated voltage: 1kv and following, and the long-term work temperature :-40 to 120 ℃, the maximum operating temperature of (1 hour) cable in short-term :≤340 ℃.Be applicable to the connecting line of aquatic building thing electric energy transmitting, illumination and control system such as various naval vessels, river seagoing vessel oceangoing ship and offshore oil platform.

Fig. 2 is the perspective view of nano environmental protection fire prevention boats and ships special wire cable.

Embodiment

Below in conjunction with drawings and Examples, further specify the utility model.

See figures.1.and.2, nano environmental protection fire prevention boats and ships special wire cable of the present utility model comprises from inside to outside successively: 3 unit cables, fire-retardant inner sheath 3, armouring 2 and fire-retardant oversheaths 1; Described unit cable comprises from inside to outside successively: conductor 7, nanometer fireproof insulating barrier 6, separator 5 and flame retardant insulation 4.

In the such scheme, nanometer fireproof insulating barrier 6 is extruded and is coated on the conductor 7, one-shot forming.

Described nanometer fireproof insulating barrier 6 employing nano environmental protection fire prevention mineral insulating materials, prescription and performance see our company's application for a patent for invention for details, and (application number: 200410000018.8), maximum operating temperature can reach 1200 ℃.

Can on the basis of conventional production equipment, mould and region of interest be undergone technological transformation, just can produce this product in batches, do not need to increase equipment frock and operation, be easy to popularize and produce and promote.

The utility model has changed the structure of traditional boats and ships special wire cable, has adopted new material, and Nai Neire, anti-naked light are anticorrosion weather-proof, has the characteristic of safety, fire prevention, anti-overload, long service life, is the renewal product of similar traditional product.
