MGTS33-24B mining optical cable 24 core underground steel wire armored cable for mining

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

　　Good compression resistance and flexibility

　　Adopt the following measures to ensure the waterproof performance of the optical cable

　　Single steel wire center reinforcement

　　Fill special fiber paste inside the loose tube

　　Cable core filling

　　Good waterproof materials prevent longitudinal water seepage of optical cables

When it does not affect identification, natural color is preferred to replace white. When there is no natural color in the fiber bundle tube, it is allowed to replace one fiber color with natural color. The specific number of cores and colors are as follows:

　　2-core: Blue, Ben;

　　4-core: Blue, Orange, Green, Ben;

　　6-core: Blue, Orange, Green, Brown, Gray, Ben;

　　8-core: Blue, Orange, Green, Brown, Grey, Ben, Red, Black;

　　10 cores: Blue, Orange, Green, Brown, Grey, Ben, Red, Black, Yellow, Purple;

　　12 cores: Blue, Orange, Green, Brown, Grey, Ben, Red, Black, Yellow, Purple, Pink, Green.
