Abstract
The utility model discloses a copper core double-insulating ceramic silicon rubber fire-resistant cable. The copper core double-insulating ceramic silicon rubber fire-resistant cable comprises an intertwisting body formed by intertwisting of three core wires, an anti-flaming halogen-free glass fiber belt layer covering the intertwisting body in a winding mode and a ceramic silicon rubber sheath covering the anti-flaming halogen-free glass fiber belt layer in a squeezing mode. Inorganic mineral materials are filled between the intertwisting body and the anti-flaming halogen-free glass fiber belt layer. Each core wire comprises a copper core conductor, a double-layer mica tape layer covering the copper core conductor in a winding mode, and a crosslinked polyethylene insulation layer covering the double-layer mica tape layer in a squeezing mode. According to the copper core double-insulating ceramic silicon rubber fire-resistant cable, the sheath is made of ceramic fire-resistant silicon rubber, can form ceramic solid bodies after high temperature or firing of flames, and is provided with a certain amount of mechanical strength and a good insulating property. Besides, when the firing time is longer and the temperature is higher, the ceramic effect is more obvious, and a role of protection of normal operation of circuits is played better.
Description
Technical field
The utility model relates to the power cable technical field, the two insulating ceramics silicon rubber back-fire relief cables of particularly a kind of copper core.
Background technology
Along with the high speed development of economic construction and people to growth in the living standard, traditional cable can not satisfy the demands.Particularly aspect safety and environmental protection, more and more high to the requirement of cable.
The traditional cable great majority all are combustible materials, and the burning back produces solid granule and forms smog, has reduced light transmittance, influence people's escape and non-refractory during breaking out of fire; Some material also contains halogen, and the pernicious gas that halogen burning back produces has very strong toxicity, the respiratory system of harm people.In addition, the halogen gas that the halogen containing polymers burning discharges can generate corrosivity pernicious gas (hydrogen halides) when combining with steam, some equipment and building are caused corrosion.And smog ihe pernicious gas is the key factor that hinders rescue and escape, cause casualties in the fire.
Though conventional silicon rubber becomes silicon dioxide attached to the cable conductor surface after burning; It has the back-fire relief performance, but the silicon dioxide after the burning is powdery, no adhesive force and certain intensity; Electric wire and cable conductor still is easy to be in contact with one another and causes short circuit, thereby fire-resistant effect is still relatively poor.
Potteryization fire-resistant silicon rubber material is to be base-material and carrier with silicon rubber; Adding has inorganic silica flour filling, constitution controller and other auxiliary agent; Through vacuum kneading, mixing, process sizing material, be sintered into the potteryization body through high temperature or flame; Have certain mechanical strength and excellent electric insulating ability, but in the back-fire relief cable, be applied so far.
The utility model content
The utility model technical problem to be solved provides the two insulating ceramics silicon rubber back-fire relief cables of a kind of copper core; Its objective is and adapt to safety and environmental requirement; Reduce the release of harmful substance at high temperature, guarantee that cable can normally move within a certain period of time after burning.
The utility model technical problem to be solved can realize through following technical scheme:
The two insulating ceramics silicon rubber back-fire relief cables of a kind of copper core; Comprise adopt three stranded intertwist bodies that form of heart yearn and wrapped on said intertwist body fire-retardant halogen-free glass fiber belt and be extruded in the ceramic silicon rubber sheath outside the said fire-retardant halogen-free glass fiber belt, between said intertwist body and fire-retardant halogen-free glass fiber belt, be filled with inorganic mineral material; Said heart yearn comprises copper core conductor and wrapped at the double-deck mica belt on the copper core conductor and be extruded in the crosslinked polyetylene insulated layer on the double-deck mica belt.
Owing to adopted technical scheme as above; Sheath in the utility model is to be material with pottery back-fire relief silicon rubber, after burning through high temperature or flame, can form the ceramic body solid; Having certain mechanical strength and excellent electric insulating can; And the time of burning is long more, and the more high potteryization effect of temperature is obvious more, can play the effect of the normal operation of protection circuit preferably.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1; The two insulating low-smoke halogen-free fire-resisting cables of a kind of copper core high flame retardant that provides among the figure; Comprise adopt three stranded intertwist bodies that form of heart yearn and wrapped on intertwist body fire-retardant halogen-free glass fiber belt 5 and be extruded in the ceramic silicon rubber sheath 6 outside the fire-retardant halogen-free glass fiber belt 5, between intertwist body and fire-retardant halogen-free glass fiber belt 5, be filled with inorganic mineral material 4; Every heart yearn comprise copper core conductor 1 with wrapped at the double-deck mica belt 2 on the copper core conductor 1 and be extruded in the crosslinked polyetylene insulated layer 3 on the double-deck mica belt 2.
