What are the types of wire model wire to identify how
Hydroelectric engineering is one of the most concerned links in our home decoration. When it comes to this, we must mention the wires and the necessary building materials for the hydropower construction. What types of wires are there ? Today we will come to understand what models are under the wire ! What type of wire 1. Use code - not labeled as power cable, K as control cable, P as signal cable; 2. Insulation code - Z oil impregnated paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; 3, conductor material code - not labeled as copper, L is aluminum; 4. Inner sheath code - Q lead package, L aluminum package, H rubber sheath, V PVC sheath; 5, derived code -D does not drip, P dry insulation; 6, outer sheath code; 7, special product code - TH wet tropical, TA dry tropical; 8, rated voltage - unit KV. How to identify the wire model 1. Use the capitalization of the first letter of the Pinyin to indicate the insulation type, conductor material, inner sheath material and structural features. For example, Z stands for paper (zhi); L for aluminum (lv); Q for lead (qian); F for phase separation (fen); ZR for flame retardant (zuran); NH for naihuo. 2, using digital representation of the outer sheath composition, there are two figures. No numbers represent unarmored layers and no outer layers. The first digit indicates armor, and the second digit indicates outer cover, as indicated by 41 for thick steel wire armored fibers. 3, the cable model according to the arrangement of the cable structure in general order: insulation material; conductor material; inner sheath; outer sheath. 4, cable products with the model, rated voltage and specifications. The method is to add the description of the rated voltage, the number of cores and the nominal cross-sectional area after the model number. As for the types of wires , I will introduce them here. I hope to help you, and more information on the decoration will be provided on this site. Stay tuned.
