Abstract
A constant temperature fireproof cable belongs to cable material technology field. A layer of metal tube which is provided with cooling medium therein is armored on the outside of the cable. Two adjacent metal tubes are serially connected on the head and tail via connection tube. High temperature resistant fireproof belt is winded on the outside of the metal tube. The fireproof belt is provided with protecting layer thereon. Exorbitant temperature of the cable can be cooled cyclically via the medium, thus the cable is always in safe temperature, the safe of the cable is ensured, and the working life is improved.
Description
Technical field
This is practical to relate to a kind of cable, belongs to the CABLE MATERIALS technical field, refers in particular to a kind of constant temperature fireproof cable.
Background technology
The high-temperature low-pressure cable is generally by the high-temperature material manufacturing at present, cable itself does not have the temperature adjusting facility, and too high or be subjected to the influence of external high temperature when the cable self-temperature, its heat can't in time discharge, cable assembly particularly insulating barrier subjects to destroy, and the cable blast can take place when serious.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency; a kind of constant temperature fireproof cable that can in time take away the cable heat is provided; guarantee the fail safe that cable uses; improve the life-span of cable; the main improvement is at fireproof cable; the metal tube of dress coolant in high-temperature cable or the armoured one deck of other analogous cable; the heat of taking away cable by the coolant in the metal tube under high-temperature condition reaches the constant temperature purpose; specifically implement like this: the constant temperature fireproof cable; the metal tube that it is characterized in that dress coolant in the armoured one deck of cable; adjacent metal pipe head and the tail are connected by tube connector; metal tube is surrounded with the fire resistant band outward, and fire guard is provided with protective layer outward in addition.Coolant in the metal tube can be water, oil or other similar cooling fluid, circulation by cooling fluid, heat when making heat that cable itself produces or cable surface be subjected to temperatures involved, taken out of by flowing of coolant, thereby guarantee the good temperature constant state of cable, the utility model is to select the diameter of cool metal pipe and use radical according to the size of the cross-section of cable.
The cable that the utility model adopts armouring to fill the nitrogen metal tube can be fireproof cable, high-temperature cable or other analogous cable, and filling the nitrogen metal tube preferably is seamless copper pipe, also can be steel pipe, compo pipe etc.
The utility model adopts the metal tube that fills coolant in cable is armoured, by the too high temperature of medium circulation cooling cable, cable is in the safe temperature all the time, has guaranteed the fail safe of cable, and be improved its useful life.
Description of drawings
Accompanying drawing is a cross section structure schematic diagram of the present utility model.
Embodiment
Embodiment 1; seamless copper pipe 2, two adjacent seamless copper pipe 2 head and the tail of dress cooling water are connected by tube connector 3 and are formed the circulation of cooling water in the constant temperature fireproof cable, fireproof cable 1 armoured one deck; metal copper pipe 2 outer wrapped fire resistant bands 4, fire guard is provided with protective layer 5 outward in addition.
Embodiment 2; the constant temperature fireproof cable; be filled with the steel pipe 2 of cold oil in high-temperature cable 1 armoured one deck; adjacent two steel pipes, 2 head and the tail form cooling circuit by tube connector 3 series connection; steel pipe 2 outer wrapped fire resistant bands 4; be provided with protective layer 5 in addition outside the fire guard 4, the outermost layer of this protective layer is that lead sheath plays radiation protection.
Claims (3)
1. the constant temperature fireproof cable is characterized in that the interior metal tube of adorning coolant of the armoured one deck of cable, and adjacent metal pipe head and the tail are by the tube connector series connection, and metal tube is surrounded with the fire resistant band outward, and fire guard is provided with protective layer outward in addition.
2. constant temperature fireproof cable according to claim 1, the cable that it is characterized in that the armouring metal tube are fireproof cable or high-temperature cable.
3. constant temperature fireproof cable according to claim 1 is characterized in that metal tube is seamless copper pipe or steel pipe or compo pipe.
