What is the lattcie structure of 3 legged tubular steel tower?
How to mount the MW dish on the 3 legged tubular steel tower?
Main structure of 3 legged tubular steel tower?
First, the structural strength is good
1. The design structure of the steel pipe tower is simple, which can effectively distribute the load of antennas, arresters, cables and other equipment, thereby improving the load-bearing capacity of the whole tower.
2. The cost of the steel pipe tower is relatively low, and it can withstand natural disasters such as strong storms and rains, and has good impact resistance and durability.
Second, easy to install
1. The structure of the steel pipe tower is exquisite, and it can be installed in a short time, which greatly saves the installation cost and time cost.
2. The steel tube tower is relatively easy to assemble and disassemble, especially suitable for applications that require frequent changes to antennas, equipment and cables.
Third,Convenient maintenance
1. The surface of the steel pipe tower is smooth and easy to clean, which can reduce the difficulty
and cost of maintenance work.
2. The steel pipe tower has a long service life and requires less maintenance and maintenance,
which saves a lot of manpower and material resources for some remote areas and harsh telecom base stations.
