Wire ropes mainly include phosphating coated wire ropes, galvanized phosphating double-coated wire ropes, stainless steel wire ropes and plastic-coated wire ropes. Water conservancy projects should use galvanized phosphating double-coated steel wire rope or galvanized steel wire rope, which has strong corrosion resistance and long service life.
As for the quota, I haven't seen the relevant regulations yet.
Overhead cable wire rope casing norm deducted 20 points.
I don't quite understand the process of cable installation and pole erection. Although I sell cables, I haven't installed them.
Armored power cables can withstand a certain tension, and if steel wires are laid outside, they should be able to withstand a greater tension.
I suggest you go to the city to see what cables, telephone lines and telephone poles are installed together and see how others do it.
Or go to the power supply station, invite your family to dinner and invite an old electrician.
What is the quota for installing steel wire rope at the waist?
The varieties of wire ropes produced in China are as follows: 1. Phosphating coated steel wire rope (China patent), phosphating film 3-60g/m2. After the steel wire is phosphatized by manganese series and zinc-manganese series, the wear resistance and corrosion resistance of steel wire rope have jumped, which greatly improves the fatigue life of steel wire rope. The fatigue life is three times that of smooth steel wire rope with the same structure (under comparable conditions in the laboratory) and far exceeds that of imported steel wire rope. Suggest doing it yourself. Phosphating coated steel wire rope is completely replacing all kinds of smooth steel wire rope, and it can also replace galvanized steel wire rope which is electroplated first and then thinned with zinc layer (corrosion resistance can be tested by salt spray test), with longer service life, lower unit use cost and better quality stability and reliability.
2. Galvanized steel wire rope, including hot galvanizing and electro-galvanizing. Generally, the galvanized zinc layer is thick, while the galvanized zinc layer is thin.
3. Stainless steel wire rope, mainly made of 304 or 3 16 stainless steel, has excellent anticorrosion effect, but it is expensive.
4. Based on plastic-coated steel wire rope and carbon steel wire rope, the outer layer is coated with polyethylene, polypropylene or nylon.
5. Smooth steel wire rope, with short service life and sharp drop in market demand, will be completely eliminated by phosphating coated steel wire rope.
6. Steel wire rope for mooring in offshore engineering
7. Wire rope
For hoisting machinery used in atmospheric environment, manganese phosphating coated wire rope is preferred, hot dip galvanized-phosphating double-coated wire rope is preferred in heavy corrosive environment, and marine wire rope is preferred in seawater. Please note that the name of wire rope, such as phosphating coated wire rope or 3 16 stainless steel wire rope, must be indicated on the purchase invoice to prevent illegal enterprises from infringing their legitimate rights and interests. In addition, patented products will generally be marked with the patent number on the outer package of steel wire rope, and the warranty should have the main technical indicators, such as the type and weight of phosphating film (phosphating film has an important impact on the service life of steel wire rope, such as wear resistance and corrosion resistance, etc.), for reference only.
How to set the quota of wire rope collar
Wire rope collars are generally divided into two types: ordinary type and weighted type.
Use a collar as large as the diameter of the wire rope.
