中心管束与层绞式电缆(国外英文资料) Cengjiaoshi cable = div= = div= cengjiaoshi cable technology The coloured fibers and ointments are added to the loose sleeves made of high modulus plastics, and the fibers can be moved in the casing. Different loose sleeves are twisted along the center reinforcing core to make the cable core. The cable core is made of protective material to make the loosely bonded fiber optic cable. Legend of stranded fiber optic cable The main features of the loosely jacketed fiber optic cable are: The loose tube material has the characteristics of hydrolysis resistance and high strength, and the tube is filled with special ointment to protect the fiber. The reinforcing core is in the central position of the cable core, and the loose sleeve is twisted around the reinforced core layer by proper twist pitch. By controlling the remaining length of the fiber and adjusting the twist pitch, the cable can have good tensile and temperature characteristics. The joint between the loose sleeve and the strengthening core is wrapped with a cable paste to ensure the waterproof performance between the loose sleeve and the reinforced core. The radial and longitudinal waterproof of optical cable are guaranteed by various measures. According to different requirements, there are many measures to prevent lateral pressure. Central tube type optical fiber cable technology The spiral space set into the high modulus fiber loose tube made of plastic casing, the casing filled with a water-resistant filling compound, applying a layer of water blocking material and sheathing materials, both sides of two parallel steel wires are placed and extruded polyethylene sheathed cable. Legend of central beam tube optical cable The main characteristics of the central tube optical cable are: The unique design of spiral groove loose sleeve is propitious to precisely control the remaining length of optical fiber and ensure the good mechanical and temperature characteristics of the fiber cable.
