Mining flame-retardant single-mode optical cable MGTS33-12B mining optical cable 12 core steel wire armored optical cable

Description :

　　Standard coal mine shaft flame retardant comprehensive optical cable MGTS33 (steel wire reinforced type)

　　Product Description: How to Translate

　　The structure of the flame retardant composite optical cable MGTS33 for standard coal mine shafts is to insert single-mode or multi-mode optical fibers into a loose sleeve made of high modulus plastic, and fill the sleeve with a water-resistant compound. The center of the cable core is a phosphorized steel wire or a phosphorized steel wire extruded with polyethylene. 5-12 loose tubes (or filling ropes and signal lines) are twisted around the center to strengthen the core and form a compact and circular cable core. The gaps inside the cable core are filled with water-resistant filling material, and the steel strip is longitudinally wrapped with an inner sheath. After the steel wires are twisted and armored, the blue flame-retardant outer sheath is used to form the cable.

　　Product Features:

　　Controlling the remaining length of the optical fiber ensures that it has good tensile performance and temperature characteristics

　　The loose tube material itself has good hydrolysis resistance and high strength. The tube is filled with special grease to provide critical protection for the optical fiber

　　Precautions for Optical Cable Installation

　　(1) Optical cables can be laid in the same way as general mining cables, but attention should be paid not to exceed the allowable tensile force, flattening force, and bending radius of the optical cable, otherwise it may cause sexual damage to the optical cable, and in severe cases, it may result in the cable being scrapped. The allowable tensile force of the optical cable during laying shall not exceed 10000N, and the tensile force of the optical cable during operation shall not exceed 4000N (which can be increased according to user requirements); The flattening force of the optical cable during laying is 3000N/100mm, and the flattening force during operation is 1000N/100mm; The allowable bending radius of the optical cable during laying is 25D, and the bending radius during operation is 12.5D.

　　(2) The ambient temperature during the installation and laying of optical cables should not be lower than -10 ℃.

　　(3) Typical values of effective group refractive index of optical fiber:

　　B1 fiber 1310nm 1.466 1550nm 1.467

　　(4) After the laying is completed, personnel should complete the connection of the optical cable. During the process of connecting the optical cable, electric sparks will be generated. Therefore, a gas safety officer should be equipped before the connection to conduct gas detection within a certain range of the connection site. When the gas concentration does not meet the safety requirements, the mine should be ventilated to reduce the gas concentration to a safe range before the optical cable can be connected.

　　The structure of the 8-core mining fiber optic cable MGXTSV-8B1 is to insert single-mode or multi-mode optical fibers into a loose sleeve made of high modulus plastic, and fill the sleeve with a water-resistant compound. The center of the cable core is a phosphated steel wire or a steel wire rope extruded with polyethylene. A loose sleeve (or filling rope and signal wire) is twisted around the center to strengthen the core and form a compact and circular cable core. The gaps inside the cable core are filled with water-resistant filling material, steel polyethylene bonded inner sheath, and then blue flame-retardant PVC sheath is used to form the cable
