Primary Connectors

FAA L-823, Styles 3 and 10, Class B

Primary circuit is the foundation of an Aeronautical Ground Lighting (AGL) system. Connectors are often the most sensitive parts of the primary circuit. Therefore, the easiest way to increase reliability of airfield light network is to favor high quality connectors.

 

Efla offers a broad range of high quality primary connectors. All Elfa primary connector product families (KDL, KD and KDR) are available for screened (shielded) and unscreened (unshielded) cable.  All of our primary connectors comply with the appropriate FAA 150/5345-26 requirements for plugs and receptacles (cable connectors). Efla’s primary connectors are packed and delivered in kits including all the necessary parts for making the assembly on primary cables. Each primary connector kit contains parts for a pair (a plug and a receptacle), resulting in a watertight post-installation connection. Nominal rating: 25 A and 5 000V.

Three types of  primary connectors:

 

KDL-SERIES

 

KDL1 Thumbnail

Mechanically secured, silicone filled primary connectors that are fast to install, reliable and have low life-time costs.

 

KD-SERIES

 

FAA-certified and silicone filled primary connectors that are fast to install, lower in purchasing price and have a proven record of over 30 years.

 

KDR-SERIES

 

Resin filled primary connectors for challenging conditions. Reliable connectors with an option for tropical resin.

 


 

 

KDL-SERIES:

KDL connectors have many unique features that make them the most reliable AGL primary network connectors. Main features of the installer friendly KDL connectors are water tightness and durability. The innovative design reduces installation time and errors.

 

KDL1 for screened / shieled cables and KDL10 for unscreened/ unshieled cables

 

 

 

Introducing the new KDL

  1. Cable gland gives excellent protection against bending and enables using any size primary cables.
  2. Connector forms screen continuity without crimping. Therefore, installation time and errors are reduced.
  3. Screen continuity without piercing the housing eliminates the risk of leakage. Universal connection point.
  4. In-build pressure equalizer makes closing the airtight connectors easy.
  5. Two-component structure on receptacle housing makes connection exceptionally reliable and long lasting.
  6. Re-usable EFLA Lock secures the connection from pulling force up to 25 kg/55 lbs.
  7. Connector water tightness is secured with Efla’s special silicon and three internal water barriers.
  8. Cable gland has rubber seal which is the primary watertight barrier between a connector and a cable.

Three elements of reliable primary connection – one solution: KDL

Reliable primary connection requires three elements. Firstly, only flawless high quality connectors should be used. Secondly, connectors need to be installed according to the instructions. Thirdly, connectors should be used correctly during system maintenance and inspections. Ignoring any of these three elements is likely to cause problems with in the primary network.

 

KDL is a new kind of connector that helps to secure all three elements influencing the reliability of primary connection. KDL is technically very reliable and long lasting connector. Innovative design makes KDL connector easy, fast and logical to install. Therefore, KDL reduces installation mistakes. KDL tolerates well bending, twisting and pulling. It withstands rough treatment in challenging conditions at the airfield. KDL allows airport maintenance personnel to focus on actual work instead of worrying about connectors at the field.

 

High Quality Connector

  • 30 years of experience and certified manufacturing and testing methods
  • Innovative details for long-lasting performance
  • Highest quality in materials and latest production methods

 

Flawless Installation

  • One connector fits all common AGL-cables
  • Installer friendly design minimizes mistakes during installation
  • Connector features reduce installation time

 

Correct Use

  • Strengthened connector structure tolerates bending well
  • Resistant to pulling, with EFLA Lock up to 25 kg
  • Optimal connector when installation space is limited
