SICON in a set: Unique connector meets modern shrink-fit technique

SICON, the patented cable connector and branch system is now available in a complete kit with modern medium voltage (MV) sleeves for the cross-section range of 50 to 300 mm² and voltage levels 10 and 20 kV. When fitting a connecting sleeve between two plastic-insulated single-core cables, PFISTERER customers are then able to choose between pure the cold-shrink technique or a combination of cold-shrink and heat-shrink techniques. In both cases, once the connection has been produced, the first thing to be fitted is a silicon cold-shrink inner sleeve: The silicon insulating body ‘parked' on a support body is simply slid over the connection point and is fitted using the cold-shrink method. For this purpose, the support body made of robust plastic is simply rolled out again under tension, making it easy to remove. The next step of the operation, the production of sheathing and cable cladding can either be performed using the cold-shrink or, alternatively, the heat-shrink technique. To finalise assembly work in a proper systematic fashion without a heat-shrink burner, or for potentially hazardous environments such as those found in the petrochemicals sector, it is advisable to employ the cold-shrink method because this avoids any heating involving the use of naked flames. Modular system, also for transitional technology To cover the entire range of possible connections, PFISTERER also offers a total system for transitional technology which is deemed to be ‘construction site ready'. As well as SICON connectors, cold-shrink silicon insulating bodies, this system includes all materials required for connecting paper-insulated three-core single lead sheath cable or belted cable with plastic-insulated single-core cable . To round off the entire portfolio, outdoor and indoor terminations for voltage levels of 10 and 20 kV are now also being offered for use with the cold-shrink fitting technique. SICON - The next generation of screw connector The infinitely variable breakaway or ‘shear-head' system of the SICON bolt eliminates the need for rated breaking points in the thread, thereby ensuring that the maximum load-bearing capacity of the thread can be exploited to its fullest extent. This process involves the breakaway point on the bolt always being at the same height as the clamp body, thereby eliminating the possibility of protruding bolt residue. The specific design of the infinitely variable breakaway bolt achieves 20 to 40 percent more contact force at the same torque level as conventional connector bolts while, at the same time, fragile cables are only clamped using the smallest possible level of contact force. This extends the life of the cable (i.e. the conductor).
