Abstract
The utility model discloses a wiring cable of a machine room which consists of a first copper conductor (1), a first isolator (2), a second copper conductor (4), a second isolator (5) and a flame retardant jacket (3). The cross sections of the first copper conductor (1) and the second copper conductor (4) are the same rectangle structures; the first isolator (2) and the second isolator (5) are arranged in parallel; the outer profiles of the cross sections of the first isolator (2) and the second isolator (5) are squares; the outer profile of the cross section of the flame retardant jacket (3) is square. As the structure is adopted, the wiring cable of the machine room has more excellent low inductance characteristics, reduces the power consumption, is smarter to transmit a signal, ensures the excellent transmission performance of the signal, is suitable for the building structure characteristics of the machine room, is easily mounted and paved, and leads the wiring of the machine room to be more convenient and beautiful.
Description
Technical field
The utility model relates to electric wire, relates in particular to a kind of machine room wiring cable.
Background technology
Employed cable in communication equipment, not only need electric energy transmitting, and want transmitting audio signal, just mean that cable can be quickly changes electric current and make a response and the inductance value of cable is low more, therefore, the machine room wiring cable that the communications equipment room wiring system is used should possess low inductance characteristic, and present machine room wiring cable electric energy loss is bigger, and there is slow phenomenon sometimes in audio transmission.
The utility model content
Technical problem to be solved in the utility model is: a kind of electric energy loss, good machine room wiring cable of guarantee signal transmission performance of reducing is provided.
Solve this technical problem, the technical solution of the utility model is: a kind of machine room wiring cable, it is made up of first copper conductor, first insulator, second copper conductor, second insulator and fire retardant jacket, the cross section of first copper conductor and second copper conductor is identical rectangle structure, first insulator and second insulator are arranged in parallel, the cross section outline of first insulator and second insulator is square, and the cross section outline of fire retardant jacket is square.
Described first insulator and second insulator are the ethylene-propylene rubber material.
Described fire retardant jacket adopts the low-smoke halogen-free polyolefin material.
A kind of machine room wiring cable of the utility model adopts such structure, compared with prior art, has better low inductance characteristic, reduced electric energy loss, the signal transmission is quick more, ensures that signal transmission performance is good, is suitable for the building structure characteristics of machine room, be easy to install and lay, make that the machine room wiring is convenient, attractive in appearance.
Description of drawings
Below in conjunction with accompanying drawing a kind of machine room wiring cable of the utility model is done explanation in further detail:
Fig. 1 is a kind of machine room wiring cable of the utility model cross sectional representation;
In Fig. 1,1, first copper conductor; 2, first insulator; 3, fire retardant jacket; 4, second copper conductor; 5, second insulator.
Embodiment
As shown in Figure 1, a kind of machine room wiring cable is made up of first copper conductor 1, first insulator 2, second copper conductor 4, second insulator 5 and fire retardant jacket 3, the cross section of first copper conductor 1 and second copper conductor 4 is identical rectangle structure, first insulator 2 and second insulator 5 are arranged in parallel, the cross section outline of first insulator 2 and second insulator 5 is square, and the cross section of fire retardant jacket 3 is square.First insulator 2 and second insulator 5 adopt the ethylene-propylene rubber material, and fire retardant jacket 3 adopts the low-smoke halogen-free polyolefin material.
The signal of telecommunication trends towards the phenomenon in the transmission of wire rod outer surface, is known as kelvin effect.Under the cross-sectional area situation identical with conditions such as length, flat rectangle conductor has bigger surface area than round conductor, and the flat conductor structure has reduced the conductor kelvin effect like this, and electric energy loss is little, and audio transmission is effective.The cross-section of cable is designed to square, is suitable for the building structure characteristics of machine room, is easy to install lay, and makes that the machine room wiring is convenient, attractive in appearance.
