Description
Technical field
The utility model patent relates to technical field of electric wires and cables, it is a kind of airfield aid photosystem that is applicable to, dimmer is to doing the electric energy transmission ﹠ distribution private cable that connects usefulness between airfield aid and the signal lamp, provide aircraft to rise and the walking path that lands, particularly, play the cable of special role in the cross-coupled place of runway.
Background technology
The kind of the airfield aid optical cable of Shi Yonging is a lot of in the market, because the principle of design and mechanical structure is different, these airfield aid optical cables all have some shortcomings of self, can not guarantee the zero-fault phenomenon when cable uses fully, comparatively speaking, rated voltage 6/6kV and following crosslinked polyetylene insulated fire-retardant resisting environmental stress and cracking airfield aid optical cable have more significant advantage, it has higher nargin safe in utilization, and the spoilage of mechanical structure is also much smaller than other cable, rated voltage 6/6kV and following crosslinked polyetylene insulated fire-retardant resisting environmental stress and cracking airfield aid optical cable are because of the meticulous selection of material, the strict control of technology when the design of super performance index and practical operation, thereby the zero-fault phenomenon can guarantee that cable uses the time.
The utility model content
The utility model is in order to satisfy the path of aircraft walking when rising with landing, particularly in the cross-coupled place of runway, the security incident of avoiding any all minor detail to cause, and can keep this good quality for a long time, the using character of cable self and its environment for use have been taken into account, transfer out signal like clockwork, at the harsh requirement of special operation under this environment to cable, I scientific research personnel of company organization has developed the airfield aid light private cable.Technical indicator and the cable design tactic pattern of innovation and the use that the special jacket material mates mutually optimized, make cable have flame retardant type, comprehensive advantage all over the body such as water proof type, cold resisting type, environment-friendly type, resisting environmental stress and cracking type, thereby the zero-fault phenomenon when having guaranteed that cable uses.
The utility model technical solution problem provides following scheme:
A kind of airfield aid light system cable that is applicable to, comprise several conductors, insulating barrier, be twisted into cable core mutually between described several conductor, described several conductor outer wrapping conductor shield, described conductor shield outer wrapping one layer insulating, described insulating barrier is coated with one deck insulation screen, and described insulation screen is coated with metal screen layer, and described metal screen layer coats one deck restrictive coating outward.
Described insulating barrier adopts cross-linking polyethylene materials.
Described conductor shield, insulating barrier, insulation screen adopt three-layer co-extruded method, make to reach even no gap between conductor shield and insulating barrier, insulating barrier and the insulation screen.
Described insulating barrier is through adopting electron accelerator irradiation.
Because the particularity of field of employment, make cable have top electric property, the lay design and the feasible practical operation of the optimal parameter when conductor is stranded, guaranteed conductor outward appearance rounding, on same three-dimensional face without any uneven phenomenon, make inner shield closely coat effectively, thereby avoided the field intensity punch-through.Conductor screen, crosslinked polyetylene insulated, insulation shielding adopt three-layer co-extruded method, make and reach the effect that even no gap coats between conductor shield and insulating barrier, insulating barrier and the insulation screen, and adopt electron accelerator irradiation crosslinked, the mechanical and physical performance of insulation and electric property are much improved; And be better than all standards at present, comprise MH/T 6049-2008 " airfield aid light circuit buried cable ".Adopt the process of three-layer co-extruded insulation make cable through after the special bend test again under the condition of 95 ℃～100 ℃ of 20 thermal cycles, stand that its discharge capacity has only 1.2pc under the 3UO voltage.Any unfavorable factor of external environment when other stops the cable use, adopt the speciality polymer material, and when operation actual parameter control, make cable have flame retardant type, comprehensive advantage all over the body such as water proof type, cold resisting type, environment-friendly type, resisting environmental stress and cracking type, thereby zero defect state when guaranteeing that cable uses.
The product structure feature explanation:
1, has top electric property, conductor screen, crosslinked polyetylene insulated, insulation shielding adopt three-layer co-extruded method, make and reach the effect that even no gap coats between conductor shield and insulating barrier, insulating barrier and the insulation screen, and adopt electron accelerator irradiation crosslinked, the mechanical and physical performance of insulation and electric property are much improved; And be better than all standards at present, comprise MH/T 6049-2008 " airfield aid light circuit buried cable ".Adopt the process of three-layer co-extruded insulation make cable through after the special bend test again under the condition of 95 ℃～100 ℃ of 20 thermal cycles, stand 3U
OIts discharge capacity is not more than 5pc under the voltage, fact proved to have only 1.2pc.
2, break through the structural design pattern of normal cable,, combine inherent with extraneous details effectively, the consideration of Parameter Optimization and extraneous unfavorable factor by calculating and reasonably production control.Zero defect state when guaranteeing that cable uses.
3, in order to guarantee the accuracy of transmission signals, adopted high-quality copper strips screen, the rate of putting up with optimizing has solved shielding and interference problem.
4, adopt the speciality polymer material, and the control of actual parameter during operation, make cable have flame retardant type, comprehensive advantage all over the body such as water proof type, cold resisting type, environment-friendly type, resisting environmental stress and cracking type.
The utility model cable innovative point:
(1) conductor
Field of employment according to the zero-fault of this special harshness, must guarantee the best electric property of transmission, not only pass through the control of strict wire drawing size, also want the lay design and feasible practical operation of optimal parameter, guaranteed conductor outward appearance rounding, on same three-dimensional face without any uneven phenomenon, make inner shield closely coat effectively, thereby avoided the field intensity punch-through.
(2) insulation
Conductor screen, crosslinked polyetylene insulated, insulation shielding adopt three-layer co-extruded method, make and reach the effect that even no gap coats between conductor shield and insulating barrier, insulating barrier and the insulation screen, and adopt electron accelerator irradiation crosslinked, the mechanical and physical performance of insulation and electric property are much improved; And be better than all standards at present, comprise MH/T 6049-2008 " airfield aid light circuit buried cable ".Adopt the process of three-layer co-extruded insulation make cable through after the special bend test again under the condition of 95 ℃～100 ℃ of 20 thermal cycles, stand 3U
OIts discharge capacity is not more than 5pc under the voltage, fact proved to have only 1.2pc.
(3) shielding
In order to guarantee that signal is not subjected to extraneous interference when transmitting, guarantee its hi-fi and stability, adopt wrapped one deck shielding to restrain the little copper strips of coefficient as shielding construction.Strict quality when wrapped optimization of putting up rate and operation is to guarantee its good shield effectiveness.
