PFISTERER joints– Always a perfect connection
Whether it's used in a switching station, HV earthing cable or offshore application, a cable connection has to be durable and safe above all else. With the joints in the IXOSIL and CONNEX product ranges, we offer the ideal solution for any connection ranging from 72 kV to 550 kV. For permanent or temporary installations and test centers, as a plug-in or built-in solution, with silicone or SF6 gas insulation, or as a compact cast resin joint which is two-thirds lighter.
Joints for permanent high voltage and earthing systems
The IXOSIL product portfolio includes slip-on joints for the entire voltage range from 72 kV to 550 kV – including various shield options, with and without bonding or earthing cables. IXOSIL joints are water-resistant and available with solid metal, plastic, or shrink-fit housing. Our tried-and-tested slip-on technology ensures secure installation and durable connections.
Speedy installation: Plug-in CONNEX joints up to 550 kV
Dry, plug-in CONNEX joints allow users to cut installation times significantly in temporary installations or offshore projects at wind farms and sea platforms where you are short on time. They are suitable for permanent connections, test installations on transformers and gas-insulated switchgears (GIS), and interim solutions for conductor and power plant construction alike. In addition to simple connection joints, CONNEX also offers elbow and tap-off joints (T-joints) plus gas-free cast resin joints up to 170 kV.
Cast resin or SF6
Plug-in cast resin CONNEX joints up to 170 kV have been providing a simplified, gas-free solution, a compact design, and lightweight structure that weighs up to two thirds less than conventional joints for over ten years. SF6 gas-insulated joints expand the voltage range up to 550 kV, are maintenance-free and up to 100% vacuum chamber tested, and are equipped with a built-in gas density monitor.
