Our Company

Hebei Changtong supply 4G Mobile single tube tower 4G communication angle steel tower 2019

Communication tower, the main structural form of four column angle steel structure, three column angle steel structure

[main function] it is mainly used for signal transmission.

[main purpose] it is used in China Mobile, China Unicom, China Telecom, China tower company and China Railway Communication Company.

[structure form] it is mainly angle steel structure.

[structure content] Q235B steel or Q345B steel or 20 ﹥ steel is generally used, all of which are hot-dip galvanized for anti-corrosion treatment, and the connecting bolts are grade 6.8. Lightning rod is set on the top of the tower, and the lightning protection grounding resistance is less than or equal to 10 ohm.

[technical parameters] wind speed resistance: 30m / s, ice coating resistance: 8mm, seismic intensity: 8 degrees, working temperature: 35-55 ℃, verticality: 1 / 1000.

Product Description

Microwave angle steel tower belongs to a kind of signal transmitting tower, also known as signal transmitting tower or signal tower. Its main function is to support signal transmitting and to support signal transmitting antenna.

Microwave angle steel tower, also known as microwave tower and microwave communication tower, is mostly built on the ground, roof and peak. The microwave tower has strong wind bearing capacity. The tower is mostly made of angle steel material supplemented by steel plate material, or all of them are made of steel pipe material. The components of the tower are connected by bolts, and all the components of the tower are treated by hot galvanizing after processing. The angle steel tower is composed of tower shoe, tower body, lightning tower, lightning rod, platform, ladder, antenna support, feeder frame and lightning down lead. It is mainly used for microwave, ultrashort wave, wireless network signal transmission and transmission. In order to ensure the normal operation of the wireless communication system, the communication antenna is usually placed at the * point to increase the service radius, so as to achieve the ideal communication effect. Communication tower plays an important role in communication network system.
