Compared with the prior art, the utility model has the advantages of low inductance, small power loss, good audio transmission effect, excellent flame retardant performance, halogen-free low-smoke and non-toxic performances that meet green environmental protection requirements, simple structure, stable performance, easy installation and nice appearance, and the cable is of large current carrying capacity, pliability and bending performance.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to low inductance DC distribution cable technology field.
Background technology
Current, fast development along with the Communication in China technology, use increasing product in the communications equipment room wiring system, as a large amount of use optical cables, five class cables, telecommunication cable and tributary distribution cable etc., simultaneously, also more and more higher to the switch cabling requirement, as each side such as electric energy loss, signal transmission effect and good looking appearances.At present, traditional machine room wiring tributary distribution cable generally adopts the typical circular conductor structure, and this structure inductance value is big, and is responsive not enough to audio signal transmission electric current reacting condition.
Technical scheme
The utility model provides a kind of above-mentioned defective that overcomes, and has low inductance, low-loss, low inductance DC distribution cable easy to use.
The technical solution of the utility model is achieved in that
The utility model comprises conductor, insulating barrier, sheath, and conductor is flat rectangle structure, and the cross-section of cable is square.
Conductor adopts TR type annealed copper wire.Insulating barrier adopts the ethylene-propylene rubber material.Oversheath adopts the low-smoke halogen-free polyolefin material.
The utility model is compared with common cable owing to adopted the flat, rectangular conductor that is arranged in parallel, and has following characteristics:
1, low inductance, electric energy loss is little, and audio transmission is effective.
2, the ampacity of cable is big.
3, cable particularly soft, good bending property.
4, fire resistance is good, has the nontoxic performance of low smoke, zero halogen, meets environment protection requirement.
5, simple in structure, stable performance, easy for installation, good looking appearance.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 is conductor among the figure, the 2nd, and insulation, the 3rd, sheath.
Specific embodiments
As shown in the figure, the utility model comprises conductor, insulating barrier and sheath, and conductor 1 is flat rectangle structure, is with many stranded the forming of the soft circular copper wire of TR type.Conductor adopts 5 class conductor structures.The flat, rectangular conductor 1 that employing is arranged in parallel can be obtained lower inductance, and surface area is big, and radiating efficiency is stronger, current load amount height.The cross section of cable is square, is easy to install lay, and insulating barrier has adopted high electrical property, low-loss ethylene-propylene rubber (ERP) material.
Oversheath adopts the nontoxic low-smoke halogen-free polyolefin material of high flame retardant.
