The application
Click-Fit joints are used in the high voltage power grids, connecting all combinations of cables with minimum effort and in less time than
conventional joints. The pre-moulded, factory tested Click-Fit joints offer a fail-safe connection every time. Click-Fit joints can be split into
four main categories. sectionalized and un-sectionalized (symmetrical joint and asymmetrical joints type to connect two different extruded
cables), transition joints for extruded to paper cable connections and branch (Y) joints. Click-Fit joints are highly reliable cable connection
assemblies designed to connect any extruded high voltage cable and able to cover a broad range of applications. Also Click-Fit technology
allows for pre-fabrication of the XLPE cable prior to disconnection of the circuit, thus reducing network down time.

Quality control
Quality control of High voltage accessories 72kV-550kV
The accessories manufactured by Click Fit in the Netherlands meet the world’s most stringent standards. The quality system in place is
responsible for the total control of quality network components and related activities. During the manufacturing process at our suppliers, all
relevant process parameters are checked and recorded. Prior to leaving the manufacturing facility, a final dimension and visual inspection is
performed.

Routine test of Click Fit Joints

The rubber electrical stress control parts of Click-fit joints are 100% successfully routine tested (FAT) before leaving the factory.
The test requirements are defined for each product family and the electrical and non-electrical test results are recorded on a
protocol. The test protocols are identified for each product by a unique code and are included with each delivery and stored for
a minimum of 10 years.

Introduction
Oil (fluid) filled (OF) and gas pressurised (GP) cable system have been long superseded by XLPE cable systems. However, there is still a vast
majority of paper insulated cables present in the network around the globe. As paper insulated cables are generally reliable, they will continue
to be a key part of the network for many years to come. Most cable manufacturers around the globe have now ceased to manufacture paper
insulated cables. In light of this, network owners are in need of a solution to ensure network reliability is achieved whilst being cost efficient.
The network is under continuous transformation, from replacing, repairing and diverting from paper insulated to solid insulation. Due to many
constraints, replacements of paper insulated cables systems can be split into two categories as shown below.

Transition Joints

Transition joints are used to connect paper insulated cable to extruded cable and include a screen interruption to isolate the cable sheaths on
each side of the joint. These type of joints are available for low, medium and high pressure cable systems. There are two main categories of
paper cables which can be connected to the extruded cable, one is the oil(fluid) filled and the other is one a gas pressurized cable. Depending
on the existing cable construction, connecting one or three core/Phase solutions is possible. Click-Fit technology allows for partial replacement
circuit to reduce cost and save time during an emergency.

CFTJX Transition Joint in operation

The Click-Fit transition joint, type CFJTX-Um, is designed to connect (oil or gas) filled paper cables with extruded (XLPE) high voltage cables.
The extruded cable ends, provided with a CLICK-FIT® plug, are inserted into the one piece pre moulded silicone rubber insulating joint body
and are electrically connected by using silver plated contacts. An integrated metallic grooved ring mechanically locks the position of the plugs
through a spring-loaded bayonet mechanism. The CLICK-FIT® plug is connected to the cable by means of compression, MIG-welding or shear-
off bolts.

The rubber Click-Fit joint insulating bodies connect the XLPE cables to bushings. The factory tested epoxy resin bushings are required to make
the transition between XLPE and paper cable parts. The paper cable part of the transition joint is created by lapping paper layers impregnated
with cable oil. The paper cable part is also provided with a connection for the oil-pressure system (pre-pressurized tank, pressure gauge, etc.).

At the paper cable side, the joint is finished with a copper casing soldered to the metal sheath. The end of the copper casing is enclosed in a
polyester outer box which provides mechanical protection and strain relief for the oil lead pipe. At the XLPE side the joint is finished with a
polymeric casing. This casing is covered with heat shrinkable tube. Both casings guarantee full radial water tightness. The installation, which
uses a minimum number of components, is user friendly and is time efficient.

CFYJ Branch Joint in operation

The Click-Fit branch joint, type CFYJ-Um, is designed to connect three extruded (XLPE) high voltage cables. The extruded cable ends, provided
with a CLICK-FIT® plug, are inserted into the one piece pre moulded silicone rubber insulating joint body and are electrically connected by
using silver plated contacts. An integrated metallic grooved ring locks the position of the plugs through a spring-loaded bayonet mechanism.
The CLICK-FIT® plug is connected to the cable by means of compression, MIG-welding or shear-off bolts. A dry type polymeric joint covering
protects against moisture ingress and mechanical impact. Vertical installation of accessories is also possible due to the integrated core
locking system. This provides a vibration proof cable system. To minimize the offshore installation time, cable ends can be prepared onshore.
The cables can then be installed and clamped inside the turbine. The installation, which uses a minimum number of components, is user
friendly, increasing the speed of installation.

CFYJ-Blind plug
For testing purpose there is a blind plug available to be adapted on the third cable exit of the epoxy Y-insulator to make HVAC- testing possible
on the other two cables connected to the Y-joint type CFYJ.
