Bolted connectors with shear-off bolts have become the established technology for connecting low voltage cables. PFISTERER offers practical complete kits for simple and professional jointing of plastic insulated low voltage cables and for transitions from paper insulated to plastic insulated low voltage cables – with more than 100 years of contact technology expertise.
Ready-to-fit complete kit
Connection and transition joint kits are supplied ready to fit. Depending on the version, they contain parts and additional materials required to install four or five-core low voltage cables up to 1 kV. In addition to heat-shrink sleeves conforming to DIN SPEC 47640, PFISTERER also offers solutions for special applications. Connection joints with a repair sleeve allow plastic insulated cables to be joined in confined spaces. Transition joints allow plastic insulated cables to be joined to paper insulated cables [N(A)KLEY and N(A)KBA].
The bolted connectors are made from high-grade aluminium with excellent electrical properties. They are resistant to chemicals and corrosion, ensuring reliable contacts and cable joints that remain stable over time. The heat-shrink sleeves are made from irradiation crosslinked semicrystalline polymers, combining high mechanical strength with excellent insulation. They are halogen-free, UV and weather resistant, and resistant to alkaline earths. On the inside, they are coated with hotmelt adhesive. This liquefies as the sleeve shrinks and makes the joint watertight when it cools down.
