TZPABP communication cable

SnabEnergoImpuls LLP offers low-frequency communication cables of the TZPABP type for delivery at competitive prices. We accept applications around the clock Explanation of the TZPABP cable: T - Telephone Z - Star four and core - twisted respectively from four insulated cores around a cord-filler and four or seven star fours P - Insulation - porous high-density polyethylene (HDPE) A - Aluminum sheath B - Armor made of two steel tapes - There is a protective polyethylene hose in the cushion under the armor. Elements of the TZPABP cable design: Core material - copper Filler - absent Screen - absent Armor - yes Core - soft copper wire with a diameter of 0.9 or 1.2 mm Insulation - porous high-quality PE pressure (PVD) Star four and core - twisted, respectively, from four insulated cores around a core filler and four or seven star fours Belt insulation - spirally applied tape of PET film and 5-7 tapes of cable paper Sheath - welded aluminum tube Protective cover - hose made of LDPE Armor - spiral armor made of two steel tapes Outer cover - glass yarn Purpose of the TZPABP cable: For installation in telephone and telegraph centers, for the installation of cable inputs and inserts in overhead lines, including with CM circuits, compacted in the spectrum up to 150 kHz, and also for the installation of connecting lines of automatic telephone exchanges and between automatic telephone exchanges and MTS. Conditions of operation and installation of the TZPABP cable: operating temperature - from -50 to +50 ° C; minimum service life under normal operating conditions - 20 years; Laying - in telephone sewers, collectors, tunnels, mines, over bridges or directly in soils of all categories that are not aggressive to steel armor and not subject to frozen deformations; laying temperature - not lower than -15 ° C ; The size of the mounting bends is at least 15 diameters along the aluminum shell. Mechanized installation is allowed with tensile forces of no more than 1500 N and no jerks. Electrical characteristics of the TZPABP cable: electrical resistance per 1 km of length at a temperature of 20 ° C, Ohm no more: - for conductive cores with a diameter of 0.9 mm - 28.30; - for conductors with a diameter of 1.2 mm - 15.85; electrical insulation resistance per 1 km of length at a temperature of 20 °C, MOhm: no less than 10,000; working capacity, nF per 1 km of length: - with a diameter of 0.9 mm - 31 ± 3; - with a diameter of 1.2 mm - 33±3 capacitive asymmetry over a length of 425 m, nF, no more: - for cores with a diameter of 0.9 mm - 800; - for cores with a diameter of 1.2 mm - 700; capacitive coupling over a length of 425 m, nF, no more than: 200 protective coefficient, no more: - with a core diameter of 0.9 mm - 0.75 - with a core diameter of 1.2 mm - 0.70 Mark size: TZPABp 4x4x0.9 TZPABp 7x4x0.9 TZPABp 12x4x0.9 TZPABp 14x4x0.9 TZPABp 19x4x0.9 TZPABp 27x4x0.9 TZPABp 37x4x0.9 TZPABp 4x4x1.2 TZPABp 7x4x1.2 TZPABp 12x4x1.2 TZPABp p 14x4x1.2 TZPABp 19x4x1.2 TZPABp 27x4x1.2 TZPABp 37x4x1. 2
