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.

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.

The new models of EJBX series junction boxes and the advantages of this series AISI316L stainless steel made

Friday, 1 July 2016

Two new models increase the EJBX family junction boxes, the smallest of the series EJBX-01 (272 x 212 x 166 mm) and EJBX-01B (272 x 212 x 142 mm).

EJBX-01 and EJBX-01B models, such as every EJBX series box, are 316L stainless steel made and manufactured with bend and welded sides: this increase the strength of the box, restricting the weldings and the possible attacks from environmental corrosive agents. The lid is wrought internally, not only externally, and milled on the internal flange with the application of a silicone o-ring which provides the IP66 protection degree if operators are mounted, and IP67 without operators. The location of the gasket ensures a constant IP protection, in addition to avoid the application of silicone grease in every opening of lid.

Compared to the majority of competitive products on the market, Cortem Group finish the whole box externally with quartz sand blasting which ensures better uniformity and appearance, more general quality of the product and an additional protection to that already guaranteed by 316L stainless steel. 

EJBX series junction boxes are complete of:

  • Cast and welded hinges which ensure more compactness and alignment between body and lid;
  • Two M6 earth screws on inside and outside of body and on lid, complete with anti-rotation brackets;
  • Stainless steel mounting brackets welded onto body with open slot, to permit more flexibility during the installation;
  • Handle for the lid opening.

Furthermore, it is possible require: 2.5mm-thick stainless steel internal mounting plate for the mounting of internal electrical components; breather and drain valve; window on lid; the color paint of external coating upon customer's request.

New LED EVL-B series floodlight

Wednesday, 1 June 2016

The new LED EVL-B series floodlights, available in two sizes EVL-60B (33W) and EVL-70B (42W), features a light and compact finned body, aluminium alloy made, which allows a fast and effective dispersion of heat generated by the normal operation of the LEDs; they are easy to install and have high lighting performance thanks tohigh intensity and efficiency LED plates which may be combined along with lens available with light beam with different shades. These lenses are capable to provide an adequate lighting for any application requirements of small and medium size, always taking into consideration an appropriate installation distance.EVL-60B floodlight reaches 2.270 lm, while the EVL-70B one has a light output of 3.700 lm.

EVL-B series can replace floodlights with traditional light sources of low and medium power such as mercury vapor floodlights of 250W and 400W. Moreover, EVL-60B series floodlight can be supplied, upon request, with colored LED to meet special needs such as the signalling of avoiding/forbidden hazardous areas (red), the presence of chemicals (green) or the need to ward off wild animals and insects (yellow).

New lamp holder for EXEL series lighting fixtures

Wednesday, 1 June 2016

EXEL series lighting fixtures are now equipped with thenew lamp holder, designed and certified by Cortem Group, and made in PBT reinforced fiberglass. The main advantage of this new accessory is that installation and replacement of fluorescent tubes are easier and safer.

The previous version of the lamp holder needed the use of both hands for the fluorescent tube insertion: holding the fluorescent tube and, at the same time, moving the spring lamp holder to align it with the two contact pins of the fluorescent tube. To insert the tube with the new lamp holder, is enough to align the contacts pins of the fluorescent tube with the lamp holder's slits and push the tube's ends until the complete insertion/hook.  During the hooking, a safety cam automatically closes itself to hold the tube. In order to replace the tube is enough to push the button which moves the safety cam on the lamp holder and unhook the fluorescent tube from contacts pulling it towards you.

EVML-50/O series lighting fixtures for tank lighting and monitoring

Monday, 1 February 2016

EVML-50/O series lighting fixtures are used to illuminate and monitor hazardous materials contained inside tanks and cisterns thanks to a stainless steel bracket for the coupling with the porthole flange. This model has a side entry in order to simplify the installation, reducing the overall dimensions.

REVF and REVN series cable glands with female and male threaded entries

Friday, 1 January 2016

REVF series cable glands, with female threaded entry, and REVN, with male threaded entry, are suitable for use in areas with risk of explosion to enable direct insertion of non armoured cables (placed in tubes or flexible pipe) in junction boxes, lighting fixtures, sockets, plugs, etc. 

They are equipped with a compression ring that tightens the cable entry ensuring the 'Ex d' way of protection and the IP66/67 protection. REVF and REVN series are equipped with an additional action point for the wrench compared to the previous FGF, FGN series cable glands, which allows the tightening of the external threaded bushing with an allen wrench. In the previous series of cable glands, in fact, the tightening of the external threaded bushing was only possible by an adjustable pipe tongs. This screw operation could ruin, scratch, engrave or even warp the ring compromising the duration and tightness. This risk has been overcome thanks to the addition of the new action point. 

For the correct assembly of REVF, REVN cable glands it’s necessary: 

- Assemble the cable gland body on the junction box/lighting fixture; 

- Assemble the side with the threaded bushing and the nut (one body) on the tube or on the flexible pipe; 

- Assemble the two parts tightening the nut.
