Product Description
Product Description
Specifications OPGW helical tension assembly, tension assembly
Grip strength:not less than 95%
rods material: Al. clad steel
70,100,120KN
OPGW helical tension assembly, tension assembly Composition: inner twisted wire, the outer twisted wire, thimble, PD-type clevis, U-type hanging ring. Purposes: to afford the whole tension, make the optical fiber composite overhead ground wire (OPGW) connect to tension tower. Features: a. uniform stress distribution, no stress concentration points, well protect fiber optic cable.
b. under the premise of not more than the lateral compressive strength of fiber optic cable the fiber, the clamp have greater holding power, able to withstand greater tension.
c. The holding force not less than fiber optic cable rated tensile strength (RTS) 95%, not damage OPGW cable at the same time.
d. high-quality aluminum-clad steel material, improve the mechanical properties of the clamp and corrosion resistance. Technical requirements: meet the DL / T 766-2003 optical fiber composite overhead ground wire (OPGW) with the preformed helical fittings technical requirements and test methods. Ordering Information:
a. According to OPGW cable rated tensile strength and diameter to select the appropriate Clamp.
b. the number of configurations: one set / Terminal Tower (including gantry); 2 sets / Tension tower.
c. The lay direction of inner twisted wire is opposite with lay direction of the outer twist wire, the standard configuration: Lay direction for OPGW outer twisted wire is right, If left, it should be specified in the order contract.
d. The clamp afford a full tension, it was proposed to use one-time.
e. provide the model type for the first tower connected with the fittings. f. Clamp strength is divided into 70kN, 100kN, 120kN and so on. Accessories and drawings:

Company Information Shijiazhuang Huaneng Electric Power Fitting Co. Ltd. is a new company with abilities of R&D,manufacture and trade. The company locates in No.189, Hengshan Street, Shijiazhuang High-tech Development Zone, Hebei Province, China, covering the area 26,593 square meters. Shijiazhuang Huaneng Electric Power Fitting Co. Ltd. specially manufactures preformed helical fittings which are widely used in transmission line. Currently our company owns the big ability to produce lots of varied preformed helical fitting in one year, among them OPGW and ADSS fittings for optical cables,together with fittings for conductor line and earth-wire line which is developed recently passed the tests in the national Electric Power Construction Research Institute and Shanghai Electric Cable Research Institute, and passed identification of the expert group of Hebei Economic and Trade committee. Our company was named as a high-tech enterprise by Hebei Science and Technique Bureau . From the beginning of establishment, we pay more attention to the quality of products, strengthened the quality conception of employees, and build up a perfect quality-control system, so we have passed the qualification of ISO 9001:2008 international quality system identification. In our company there are enough experts and advanced equipments for production and examinations, Our products have been sold to many localities in nation and overseas, and been used in lines of different voltage degree. Suffering the rigorous test in every kind of weather conditional, our products still work very well without any trouble occurrence. In order to offer the customer a exact and effective plan of reduce-vibration , Our company established a vibration-laboratory with the help of transmission line experts and the vibrate experts of the national power company. We can test the power characteristic and tired function of vibration damper, and test it’s reduce-vibration valuation in the the OPGW and ADSS optical cables, consequently providing a scientific trial basis for design of reduce-vibration in the projects. Our quality guideline: Regarding customer as our focus with attention, persisting in innovating in techniques, strengthening and perfecting quality-control system, providing the high-tech product for electric power developments.
