What are the main features of the network three-in-one lightning arrester?

Three-in-one lightning protection device, including: three-in-one lightning protection device, three-in-one video monitoring lightning protection device, monitoring three-in-one lightning protection device, three-in-one arrester, monitoring three-in-one arrester, three-in-one camera lightning protection Device, video surveillance lightning protection device, camera lightning protection device, camera lightning protection device is the alias of the lightning protection device. The three-in-one lightning protection device, also called combination lightning arrester and monitoring multi-function lightning protection box, refers to the lightning protection equipment that integrates the video lightning protection and the power supply lightning protection of the camera end in the monitoring system.

Three-in-one lightning protection device features

â—† Three-in-one lightning protector is used to protect the 2-core data transmission line, and the port is the connection terminal.

â—† Three-in-one lightning protection device is suitable for lightning protection of high-speed ball, medium-speed ball and PTZ camera.

â—† Three-in-one lightning protection device integrates the surge protection design of the monitoring camera's power supply, video, and control lines to balance the potential difference of each line.

â—† Three-in-one lightning protector can effectively prevent equipment damage caused by instantaneous increase of potential difference such as power supply, video, and control line.

â—† Three-in-one lightning protector has large flow, low residual pressure, fast response, and long service life.

â—† The three-in-one lightning arrester is collectable, small in size, easy to connect, and easy to install.

Cold Drawn Steel Bar
Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.

For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.

To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).

For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.

We have more advantages on producing cold drawn steel bars:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm

3) Different cold drawing medias powder or oil to get different surface

4) Straightening machines to get better straightness up to 0.5mm/m

5) Grinding and polishing machines to get better roughness upto 0.4um

6) Heat treating furnaces to adjust the mechanical properties

7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

8) Multiple packages to avoid broken packages and anti-rusty
