COMMENTS 1. The catalog is arranged in order of products type and their use, including six categories: suspension clamp, strain clamp, link fitting, splicing fitting, protective fitting and guy-wire fitting. Every category can be divided into several series according to products’ structure and their use. 2. Catalog symbols of the fittings consist of Chinese phonetic alphabet, Arabic numerals and additional letters, their meanings are as follows: Additional letter Main parameter—conductor size, failure load, spacing size The second and the third letter—type, structure, effect The first letter—category 3. In this catalog, there are only the outer diameter of the compression pipe and the specification of suitable conductor for the strain clamp and splice sleeve, the parameters of conductors are shown in the Appendix. 4. The diameter of suitable conductor for suspension clamp, parallel groove or vibration damper is the outermost diameter of the conductor with its wrap, such as aluminum tape, armor rods, etc. 5. If the line fittings you need are not in this catalog, we can design and produce all kinds of fitting products according to the specific requirements of projects. 6. Bolt torques of the bolted fittings are recommended as follows (mild steel): Bolt diameter(mm) 8 10 12 14 16 18 20 Torque (N·m) 19 22 36 50 65 83 105 7. The technical specifications of the products in the catalog are in accordance with Chinese Standard GB/T 2314-2008 and specific standards of the manufacturer own. “`
