Shielding Earth Braid

The Shielding Earth Braid is used to isolate electromagnetic field noise sources from sensitive devices and cut off the propagation path of the noise sources. Shielding Earth Braid is divided into active shielding and passive shielding. Active shielding is to prevent noise sources from radiating outward. Passive shielding is designed to prevent sensitive equipment from being interfered by noise sources.

Product Description

Shielding Earth Braid


1.Product Introduction 


The Shielding Earth Braid is a permanent good electrical connection between the shielding body and the ground or the metal housing of the interference source in order to prevent electromagnetic interference. The Shielding Earth Braid is used to isolate electromagnetic field noise sources from sensitive devices and cut off the propagation path of the noise sources.  Shielding Earth Braid is divided into active shielding and passive shielding. Active shielding is to prevent noise sources from radiating outward. Passive shielding is designed to prevent sensitive equipment from being interfered by noise sources.   


Shielding Earth Braid


The Shielding Earth Braid is mainly made of copper, aluminum and other non-magnetic materials, and the thickness is very thin, is far less than the skin depth of metal materials, using frequency not shield effect is mainly due to the metal body itself of the electric field, magnetic field of reflection, absorption and produce, but due to shield grounding, grounding form different will directly affect the shielding effect. The grounding method for electric and magnetic shielding layer is different. It can be ungrounded, single-grounded, or double-grounded. Our company has an independent factory site with the building area of 27000 square meters, the land area of more than 14300 square meters. Product testing equipment is complete, with nano electron accelerator, injection moulding machine, rubber molding machine and other production and manufacturing equipment. Also it has high pressure screening test center, fully meet the needs of product inspection and testing.

3.Product Feature And Application 


1. The single grounding of the Shielding Earth Braid is helpful to avoid the interference of low frequency electric field. Or it can avoid frequency interference whose wavelength λ is much larger than the cable length L. 
2. Single grounding of the Shielding Earth Braid can avoid low frequency current noise on the shield. This current internally causes common mode interference voltage and may interfere with analog devices.

3. Generally, the transmission impedance of the metal foil shielding layer is much greater than that of the copper braided wire shielding layer, and its effect is 5-10 times different, so it cannot be used as a digital signal cable.  

4. Shielding multipoint grounding is advantageous except at cable endpoints.

5.Product Qualification


The production of heat-shrinkable cable accessories needs to go through a series of processes such as Mixing → Forming → Irradiation → Expansion → Gluing. Shape memory effect of polymer materials is the basic principle of fabricating heat-shrinkable materials. The characteristics of the polymer material itself give the heat shrinkable cable accessories with good electrical and mechanical properties, light weight, easy installation and other advantages. The product is waterproof, stress control, shielding, insulation in one, can be used in a variety of harsh environmental conditions for a long time. Widely used in Electric Power Industry, Petroleum Industry, Chemical Industry, Metallurgy, Railway, Port, Construction and other fields.
