¡¡¡¡Description

¡¡¡¡The communication tower is also called a signal-launching tower or a signal tower. It mainly serves to support signal transmitting antenna of launching signals in communicative sectors, like China Mobile, China Unicom, China Telecom, and transportation satellite positioning system (GPS).

¡¡¡¡I) features and usage

¡¡¡¡a) Classification: it falls into two categories: a ground communication tower and a roof communication tower (also known as communication iron tower). No matter where users choose to erect the tower, on the ground or hills or mountains or on the top of a building, it plays the role of heightening the communication antennas.

¡¡¡¡b) The tower can amplify the service scope of the communication signals or television signals, maximizing the communicative effects. In addition, the roof communication tower plays the role of lightning protection and grounding, beautificication and aviation warnings.

¡¡¡¡c) The tower is mainly used to erect singal launching antennas or microwave transmission equipment in various sectors like China Mobile, China Telecom, China Unicom, Public Security bureau, troops, railway and broadcast and television sectors, so it is also called a microwave communication tower

¡¡¡¡II) Productive technology

¡¡¡¡The communication tower comprises of tower body, platform, lightning rod, ladder, antenna support and other steel componnents. After hot dip galvanizing treatment, it is mainly used to transmit and launch microwaves, ultrashort waves and wireless network signals. In order to ensure the normal operation of the wireless communication system, communication antennas are generally placed on the highest point of the services in order to increase communication radius to achieve the desired effect. Communications antennas must have a communication tower to help increase the height of the communication tower£¬so the tower plays an important role in the communication network system.

¡¡¡¡III) Application Scope

¡¡¡¡China Mobile, China Telecom, China Unicom, Public Security bureau, transportantion, troops and so on.

¡¡¡¡IV) Technical parameters

¡¡¡¡Design height:

¡¡¡¡5m-180 m (ground tower, four-post angle steeel, four-post steel pipe, cable tower)

¡¡¡¡5m -40 m (roof tower, four-post angle steel tower, aluminum alloy tower,)

¡¡¡¡10m -60 m (ground tower, three-post tube tower, monopole tower)

¡¡¡¡Designed wind speed: 28-32M / S

¡¡¡¡Wrapped ice: 5-10mm

¡¡¡¡Seismic intensity: magnitude 8

¡¡¡¡Suitable temperature: -45 ¡æ -- 45 ¡æ

¡¡¡¡Vertical deviation: <1/1500

¡¡¡¡Grounding resistance: ≤ 4Ω

¡¡¡¡Antiseptic treatment: hot dip galvanizing (commonly rustless for 30 years) or painting (commonly rustless for 2-5 years)

¡¡¡¡Safety factor: 4 times

¡¡¡¡Material origin: Baogang Group, Shoudang Group, Handan Iron & Steel Group, Tangshan Iron &Steel Group etc.

¡¡¡¡V.Classification of communication towers

¡¡¡¡Category£ºfour-post angle steel towers (self-supporting or guyed), four-post steel-pipe tower (self-supporting or guyed), three-post steel-pipe tower (self-supporting or guyed), single-pipe tower( monopole tower), guyed towers.

¡¡¡¡Steel-pipe tower: it falls into two categories: four-post or three-post steel-pipe tower; advantage: under the same designed conditions, it is characterized by high stability, strong capacity of wind and seismic resistance. Angle steel towers, single-pipe towers and guyed (cable) towers are suitable for narrow sites or sites which are closer the building. Nowadays they are widely used in high speed rail in China.

¡¡¡¡Angle steel tower: as the most common type of tower, it is easy and economical to manufacture and install, so it is the preferred choice in tower constructions;

¡¡¡¡Guyed (cable) tower: less consumption of steel, economical and practical;
