The utility model will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, present embodiment is a kind of square cable for telecommunication equipment, and the integral body of this cable is positive square structure.Cable core is made up of two conductor thread cores 1, and conductor thread core 1 is a tinned conductor, is positioned at the center of cable.Two rectangle conductor thread cores 1 be arranged in parallel, the every conductor thread core 1 outer flame-retardant low-smoke halogen-free insulating barrier 2 that is respectively installed with rectangle structure, two rectangle conductor thread cores 1 that be arranged in parallel and be sleeved on that its outside flame-retardant low-smoke halogen-free insulating barrier 2 is common forms square type structure, the vertical alclad plastic composite strip 3 of the outside suit of this positive square structure constitutes plastic-aluminum combined belt, vertical alclad plastic composite strip 3 outer braiding tinned copper wires 4, vertical alclad plastic composite strip 3, tinned copper wire 4 mutual group quadrate screens, the outside suit square of square screen flame-retardant low-smoke halogen-free sheath 5.
The flame-retardant low-smoke halogen-free material is environment-friendly materials, and is nontoxic, selects insulation and the sheath of this material as cable, and purpose is to improve the environmental-protecting performance of cable, is convenient to high-accuracy electrical equipment telecommunication apparatus and uses.
During making, insulated wire cores is stood up when preventing the parallel braiding of cable, horizontal caterpillar-tractor is adopted in traction, unwrapping wire adds rocker with take-up place and guarantees that core is parallel, smooth, do not stand up, conductor thread core 1 adopts five class strands structures, every conductor thread core divides three bursts of parallel placements, use the flame-retardant low-smoke halogen-free polyolefin to extrude rectangle insulating barrier 2, rectangle insulated electric conductor core by two parallel placements is formed square structure, vertical alclad plastic composite strip 3 weaves tinned copper wire 4 composition screens simultaneously outside vertical alclad plastic composite strip 3 outside positive square structure, extrudes flame-retardant low-smoke halogen-free polyolefin square sheath 5 outside screen.
By to 2X6mm
2Circular and rectangle electric capacity, inductance measurement contrast, and circular electric capacity is 205PF/M, and square capacitance is 520PF/M, and circular inductor is 710uH, and square inductance is 31uH, realize low inductance of product and big electric capacity, make cable eliminate clutter under high electromagnetic compatible environment.
