Description
Technical field
The utility model relates to fireproof cable technical field, especially a kind of double isolated flexible mineral fireproof cables.
Background technique
With era development and scientific and technological progress, this cable in the prior art is no longer satisfied modernization development
Demand, such as skyscraper, tunnel, airport place multicore long length cabling requirements increasingly increase, these places require
The cable fire time is long, and is produced with original old technique, and main thinking is how the cable that catches fire prevents fires, and such case is past
It under the high-temperature condition generated toward fire, is just easy to make existing cable bad, and leads to heavy economic losses and generate serious
Social influence.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of double isolated flexible mineral fireproof cables, improve cable
Fire protecting performance.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:, and a kind of double isolated flexible mineral are anti-
Thermoelectricity cable, including multiple cores, the core include conductor, have ceramic silica gel, the pottery in the external sheath of conductor
Aluminum pipe is equipped on the outside of porcelain SiClx glue；Ceramic silica gel is heat-resisting can to reach 300 degrees Celsius, easily squeeze out, and extruded velocity is fast.
The outside of the core is coated with flame retardant coating, and the outside of the flame retardant coating is coated with aluminum hose, in aluminum hose
Outside be equipped with sheath.
Preferably, cross-linked polyethylene layer is additionally provided between the ceramic silica gel and aluminum pipe, the cross-linked polyethylene layer
Outer surface is laciniation.Being set as laciniation keeps cross-linked polyethylene layer intensity high, is easy to fire resisting formable layer.And it prevents
Aluminum pipe damages ceramic silica gel.
Preferably, the conductor includes round core, the first segment conductor-core is coated in the outside of round core, first
The outside of segment conductor-core is coated with the second segment conductor-core.
Preferably, be equipped between ceramic silica gel and conductor and between ceramic silica gel and cross-linked polyethylene layer mica around
Covering.Wrapped mica is easy to the molding of ceramic silica gel, improves conductor electric conductivity.
Preferably, the flame retardant coating uses fire-proof mud.
A kind of double isolated flexible mineral fireproof cables provided by the utility model, using the form of bilayer isolation, using double
Layer protective metal shell, air insulated twice, outermost metal sheath is embossing mode, resistance under the premise of guaranteeing good bending property
Fiery temperature can reach 1000 degrees Celsius, be kept for 4-5 hour of cable normal power-up.And aluminum material is used, and save the cost, production

Preferably, the flame retardant coating 5 uses fire-proof mud.
A kind of double isolated flexible mineral fireproof cables provided by the utility model, using the form of bilayer isolation, using double
Layer protective metal shell, air insulated twice, outermost metal sheath is embossing mode, resistance under the premise of guaranteeing good bending property
Fiery temperature can reach 1000 degrees Celsius, be kept for 4-5 hour of cable normal power-up.And aluminum material is used, and save the cost, production
Speed is fast.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim
The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model
Protection scope within.
