LED traffic light units with Wi-Fi system TL series

Wednesday, 31 January 2018
TL series Wi-Fi traffic lights have been designed to control roadway junctions in hazardous areas using the technology of RF (radio frequency) communication.
It is common knowledge that individual units must communicate with one another for the purpose of coordinating the correct light colour to display to flowing traffic. The use of RF technology eliminates the need to dig up the road surface in order to "bury" the cables and/or sensors required in the systems used today.
In addition, Wi-Fi technology facilitates the use of a traffic light system in situations where a short-term solution, rather than a permanent installation, is required.


New signalling lighting fixtures EVL-60B/G, EVML-50/G

Monday, 24 July 2017

EVL-60B/G and EVML-50/G are the new lighting fixtures which feature a LED plate and a globe of different colours: blue, red, green, amber.

They can be installed in locations where obstacles, dangers must be signalled and for any visual communication. They replace acoustic signals in places where they are not applicable.


New accessory for EVF-18EX series lighting fixture

Monday, 24 July 2017

Some standardized pictograms according to UNI EN ISO 7010 have been codified, however, other safety pictograms can be provided on specific customer request.

REVD series Cortem Group cable glands positively passed the EMC tests for electromagnetic compatibility

Monday, 20 March 2017
The EMC Directive 2014/30/EU (Electromagnetic Compatibility) states that electrical equipment must not cause interference or electromagnetic pollution. They shall also be immune to a reasonable amount of interference.
Cable glands are not components under the EMC Directive because do not emit electromagnetic interference and they cannot suffer them.
However, the cable glands with good electrical continuity properties, can significantly improve the EMC performance of equipment connected to cables secured with cable glands, providing an electrical continuity path for the cable shield.
Cortem Group conducted at Intertek laboratory the EMC tests on REVD cable glands for armored cables of various sizes in an anechoic chamber. The cable glands were installed in a flameproof enclosure with a connected cable section, having function of antenna. A generator of electromagnetic radiation was introduced into the junction box and it has been measured the level of the cable shield radiation.
The test showed that if the shield/armor is properly connected to Cortem Group cable gland, detected emissions are well below the Class B levels set out in EN 55022 standard. The levels are also acceptable if the shield/armor is partially connected. In any case, attenuations of the disorder up to 20-30dB occur, depending on the frequencies.
This demonstrates the excellent quality of electrical continuity of REVD Cortem Group cable glands.
