This product is a series of mining rubber cable. It is suitable for power connection of coal mining machine and similar equipment with rated voltage Uo / U of 1.9 / 3.3KV and below. Mostly used in coal mines.
Conditions of use
The long-term allowable working temperature of the core is 65 ° C, and the minimum bending radius of the wire is 6 times the cable diameter. Yellow-sheathed cables must not be exposed to sunlight for long periods of time.
Scope of application
· This product is suitable for control and signal connection cables used in nuclear power plant rated voltage Uo / U of 0.6 / 1kV control system network.
· The long-term working temperature of the cable conductor is 90 ℃. The maximum temperature of the cable conductor during short-circuit does not exceed 250 ℃, and the duration does not exceed 5 seconds.
· The ambient temperature when laying the cable should not be lower than 0 ℃.
· The allowable bending radius when laying the cable is:
— Unarmored cables, not less than 6 times the cable diameter
— For cables with armored or copper tape shielding results, Zhengzhou wire and cable should not be less than 12 times the diameter
— Flexible cables with shielded structure should not be less than 6 times the cable diameter.
When the long-term allowable working temperature of the conductor is not more than 90 ° C, the identification life of the cable is not less than 40 years.
· The finished cable should meet the requirements of Class A bundled combustion test specified in the GB / T18380.3 standard.
· Finished cable smoke density: light transmittance is not less than 70%.
· Radiation resistance: 25 × 104Gy
· Halogen-free: When non-metallic materials are burned, the acidity (expressed as PH value) of the escaping gas should be greater than 4.3; the conductivity should not be greater than 10 μS / mm.
Bare wires and bare conductor products
The main characteristics of this type of product are: pure conductor metal, no insulation and sheath, such as steel core aluminum stranded wire, copper and aluminum bus bar, electric locomotive wire, etc .; the processing technology is mainly pressure processing, such as melting, rolling, drawing System, twisting / compact twisting, etc. The products are mainly used in suburbs, rural areas, customer main lines, switch cabinets, etc.
The products are mainly used for the transmission of strong electric energy in power generation, distribution, transmission, transformation, and power supply lines, with large currents (tens of amps to thousands of amps) and high voltages (220V to 500kV and above).
Communication cables and optical fibers
With the rapid development of the communications industry over the past two decades, products have also developed at an alarming rate. From simple telephone and telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structure size of such products is usually small and uniform, and the manufacturing accuracy is high.
Electromagnetic wire (winding wire)
Mainly used for various motors, instruments and so on.
