The cable is passed through the tightening neck and sealing O-ring. The veins need to be suitably shortened, stripped and shaped. After inserting the wires into the central part of the jumper, the screws are fixed and the tightening neck is properly tightened. At the outlet, thinner flanges are used, which are passed through the sealing O-ring and then connected by a tube.
The design has an IP68 degree of protection, i.e. withstands immersion in water. The actual material from which the jumper is made shows excellent resistance to mechanical damage or various chemicals. It is permanent, does not age and its properties do not change depending on the surrounding atmospheric conditions.
This is a less common division of a three-core cable into two. Typical use is for SMART lights that are controlled via the LIN bus. If the same bus is used in the vicinity of the light fixture to control other appliances and the installation is carried out with the help of CYKY/CYSY cables, it is advisable to apply this connector.
In the overview, we present it for the case when, either for conservatively traditional reasons, the installer wants to use a 3-core CYKY cable for SMART lights, or it is a case of refurbishing old lights in lighting locations where he does not want to remake the existing CYKY cabling. This jumper is used for the output terminal 313-LD-48/LIN CYKY. However, it is necessary to specify that the lamps also have an output terminal for the CYKY cable.
