Description
Technical field：
Cable is the utility model is related to, mainly a kind of air-tightness cable.
Background technology：
On special occasions, as the cable on laboratory or warship will use in a humid environment, thus need to protect
Hold good air-tightness and water resistance, prior art is single in the cable airtight construction that this special occasions uses, mostly
It is only poor filled with the fluid sealant that structure is single, sealing performance in cable.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of air-tightness cable, to solve existing for prior art
Technical problem..
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of air-tightness cable, includes copper conductor, it is characterised in that：Described copper conductor is twisted by more oxygen-free coppers
Composition, and solidify to form airtight structure filled with extraordinary liquid-state silicon gel in twisted gap, described copper conductor is coated with
Crosslinked polyetylene insulated layer, extraordinary liquid-state silicon gel is filled with crosslinked polyetylene insulated layer interior sealing, the crosslinked polyethylene is exhausted
Edge layer is coated with LSOH anti-flaming inner restrictive coating, and water-blocking buffer layer is provided with LSOH anti-flaming inner restrictive coating, described
Water-blocking buffer layer be waterproof paste and water-proofing powder mixture；It is low that described LSOH anti-flaming inner restrictive coating is coated with Halogen
The fire-retardant external sheath layer of cigarette, aluminium-polyethylene is provided between LSOH anti-flaming external sheath layer and LSOH anti-flaming inner restrictive coating
Tack coat.
Described aluminium-polyethylene bonding layer and LSOH anti-flaming inner restrictive coating and LSOH anti-flaming external sheath layer it
Between be filled with high temperature oxidation resisting magnesium ceramic powders.
The utility model has the advantages that：
Copper conductor is twisted using oxygen-free copper in the utility model, and the stable electric conductivity of structurally flexible is superior, is noted when twisted
Enter extraordinary liquid-state silicon gel to solidify by special process, form an air-locked overall structure to carry out sealing filling to conductor,
Make conductor integrally airtight；And the cross-linked polyethylene insulated cable material that insulate, insulation electrical performance are high, light specific gravity, good mechanical property；
Extraordinary liquid-state silicon gel is injected between insulating barrier and copper conductor again by special process solidification to carry out being again sealed off filling out to cable core
Fill, form an air-locked overall structure to carry out sealing filling to cable core；Sheath uses smoke halogen-free flame retardant sheath material, tool
There is waterproof and dampproof wet effect, and have the function that low smoke, zero halogen prevents burning；Water-blocking buffer layer is additionally provided with simultaneously, can increase and block water
Prevent close performance, this air-tightness cable can be accomplished to cut within 1 meter of cable, more than the pa of air pressure 800 air tight.
