With the rapid development of electric power and electronic technology, the automation of electrical system has been continuously improved, and the confusion brought by electromagnetic interference has also followed. It is essential to eliminate electromagnetic interference (EMI, EMP) in power and electronic systems. In some special occasions, such as nuclear power, military industry, and large-scale power equipment, it is also necessary to consider the electronic countermeasure capability during the war to avoid the impact of electromagnetic pulse bombs that paralyze the entire system.

In view of the above special requirements, the specially developed and produced sealing module with shielding (ES, PE) and grounding (BG) functions is combined with the conventional sealing module, which greatly reduces the conduction of electromagnetic interference signals along the cable shielding layer (360 wrapping around, eliminating the "pig tail" effect) and greatly reduces the space conduction interference.

Cable Sealing Solution with Electromagnetic Protection Function

Protective purpose: the specially designed module blocks the diversion radiation, conducts electromagnetic interference, and blocks all kinds of electromagnetic interference outside the wall.

Mechanism of action: copper foil or copper braided tape is embedded in the module, and the copper foil or copper braided tape and the cable shielding layer form a 360 ° package. Interference signals conducted on the shielding layer are introduced into the earth through a grounded metal frame, which is generally installed at the cable entrances of shielding rooms, control rooms, computer rooms, etc.

The semiconductor chip clamped in the module will conduct space radiation to the copper foil, which will be conducted to the grounded metal frame. Such products often cooperate with the shielding of vehicle shells and buildings to form a complete Faraday cage to shield external space radiation.
Conductive copper foil: The conductive copper foil can wrap the cable shielding layer or metal pipe at 360 ° to form a low impedance grounding path and shield the high frequency radiation and conduction in the environment.

Heavy-duty conductive braided tape: The use of heavy-duty high-power braided tape can reliably ground armored cables or shielded cables, and introduce lightning strikes, short circuits or surge currents into the common grounding terminal to protect equipment from damage.

There are three different types of shielding modules according to different application scenarios and requirements.

ES: It can not only reduce the space conduction interference, but also reduce the conduction interference of the conductor conduction layer (cable shielding layer);
These modules, frameworks and accessories form a comprehensive electromagnetic defense system, which can deal with various types of electromagnetic interference that may occur, such:

● Power frequency interference generated by high-power power generation equipment

● Pulse generated by the action of circuit breaker, switch and knife switch

● Lightning, short circuit and surge current

● Signal interference caused by mobile phones and other electronic devices to sensitive electronic devices, etc.
