Abstract
The invention relates to a medium-voltage fireproof termite-resisting cable which includes at least three conductors with insulators. The insulators are crosslinked-polyethylene insulators. A conductor shield is arranged between each conductor and a corresponding insulator. An insulating shield, a copper-tape shield and a phase-splitting fireproof layer lap the insulator of each conductor. A ceramic silicone rubber composite tape I, an oxygen isolation layer, a ceramic silicon rubber composite tape II, a copper pipe and a protective sleeve wrap the three conductors sequentially. A filling rope is arranged between the three conductors and the ceramic silicon rubber composite tape I. The filling rope is an inorganic paper filling rope. The oxygen isolation layer is a low-smoke halogen-free polyolefin oxygen isolation layer. The protective layer is a nylon protective sleeve of high-density polyethylene. The conductor shields and the insulating shields are semi-conductive crosslinked-polyethylene shields. The copper pipe is a longitudinally wrapped argon-arc-welding corrugated pipe. The medium-voltage fireproof termite-resisting cable is significantly great in fireproof performance, capable of reaching a fireproof grade of a mineral insulating cable and high in mechanical strength.
Description
Technical field
The present invention relates to press in one fire-resisting cable, press fire-resistant anti-termite cable in specifically.
Background technology
The fire-resistant effect of tradition fire-resisting cable is unsatisfactory, and bad mechanical strength, does not have oil preventing performance and does not also have waterproof, anticorrosion, termite-proof performance.
Summary of the invention
The present invention is intended to overcome the defect of prior art, provides in one and presses fire-resistant anti-termite cable, and fire resistance is extremely excellent, can reach the fire-resistant rank of mineral insulated cable, and cable machinery intensity is high.
In order to solve the problems of the technologies described above, the present invention is achieved in that
In one, press fire-resistant anti-termite cable, it comprises at least three conductors with insulation, it is characterized in that: described insulation is crosslinked polyetylene insulated, between each conductor and insulation, be provided with conductor screen, the outer lapped insulation shielding of insulation, copper strip shielding and the phase-splitting flame retardant coating of each conductor, three conductors are surrounded by pottery silicon rubber composite band first, oxygen barrier layer, pottery silicon rubber composite band second, copper pipe and sheath outward successively, between three conductors and pottery silicon rubber composite band first, are provided with gasket for packing.
The described fire-resistant anti-termite cable of middle pressure, is characterized in that: described gasket for packing is inorganic paper filling rope.
The described fire-resistant anti-termite cable of middle pressure, is characterized in that: described oxygen barrier layer is low-smoke halogen-free polyolefin oxygen barrier layer.
The described fire-resistant anti-termite cable of middle pressure, is characterized in that: the nylon sheath wire that described sheath is high density polyethylene (HDPE).
The described fire-resistant anti-termite cable of middle pressure, is characterized in that: described conductor screen and insulation shielding are the shielding of semiconductive crosslinked polyethylene.
The described fire-resistant anti-termite cable of middle pressure, is characterized in that: described copper pipe is vertical bag argon arc welding ripple copper pipe.
The invention has the beneficial effects as follows: fire resistance is extremely excellent, can reach the fire-resistant rank of mineral insulated cable, cable machinery intensity is high, waterproof, grease proofing, corrosion-resistant, termite-proof performance are splendid, cable lateral pressure resistant, malleation performance, water resistance are splendid, can under certain depth of water, use for a long time, meeting particular client can the super fire-resistant extremely property requirement of waterproof again to midium voltage cable.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1: in one, press fire-resistant anti-termite cable, it comprises at least three conductors 1 with insulation 3, described insulation 3 is crosslinked polyetylene insulated, between each conductor 1 and insulation 3, be provided with conductor screen 2, the outer lapped insulation shielding 4 of insulation 3 of each conductor, copper strip shielding 5 and phase-splitting flame retardant coating 6, three conductors are surrounded by pottery silicon rubber composite band first 8 outward successively, oxygen barrier layer 9, pottery silicon rubber composite band second 10, copper pipe 11 and sheath 12, between three conductors 1 and pottery silicon rubber composite band first 8, be provided with gasket for packing 7, described gasket for packing 7 is inorganic paper filling rope, described oxygen barrier layer 9 is low-smoke halogen-free polyolefin oxygen barrier layer, the nylon sheath wire that described sheath 12 is high density polyethylene (HDPE), described conductor screen 2 and insulation shielding 4 are the shielding of semiconductive crosslinked polyethylene, described copper pipe 11 is vertical bag argon arc welding ripple copper pipe.
