Shielded Tent

Gtemcell offers an innovative shielding product made of a highly conductive double layer of aluminum with internal reinforcing mesh in polyester for the coating and creation of shielded environments within pre-existing structures. The application frequencies range from a few Mega Hertz to several GHz with an electric field attenuation of 45-80dB. The great advantage is ease of application even on curved and complex surfaces and lower costs which make this application particularly attractive. GTEMCELL supplies the shielded fabric or performs all the environmental shielding work. The aesthetic finishes are the responsibility of the customer.
The construction includes a preliminary inspection to evaluate all the "critical" aspects such as the openings present: doors. windows, air conditioning systems, electrical connections and consequently draw up an economic evaluation of the costs.

Theory of operation, Introduction

GTEMCELL offers Faraday’s principle-based chamber for electromagnetic shielding.

A tent made of special coupled metalized Cu-Ni tissue offers an easy way to make a screened ambient whenever it needs a shielding solution with a lightweight for transportation and fast installation GTEMCELL is there.

The tent structure is made in aluminum frame tubes or in steel rods customized in dimensions and openings.

The open side (door): It is made with a Velcro electrically conductive and with a ZIP metal with conductive fabric as support to ensure the conductivity of the two sides of the part of the tent. The adequate size of overlapping of the conductive fabric ensures good shielding.

The fabric is covered with a coating flame retardant also able to ensure a good abrasion resistance to the conductive surface. The flexibility is tested according to AFNOR G52-020 .

Window: A ready-to-use metal mesh fabric panel offer a view from outside and inside or vice-versa; size Aprx. 300 mm x 300 mm

Inside on the fabric surface: The electroless process offers a strong adhesion of the nickel 100% to the surface of polyester yarn all around. On the macro photo, the deposition is uniform
