Type of Electrical Connectors

Substations are a key point of electrical networks and need to be highly reliable to support growing electrical demands. For high voltage substations from 60 kV to 550 kV we offer:

• High voltage clamps and connectors: Our range of SIMABUS and SIMAFLEX clamps and connectors are for AC and DC applications up to 500 kV. They are made to connect aluminum tubes and overhead bare conductors.
• Earthing stirrups, end caps and spacers

Underground power grids require reliable and durable products that are easy to install and support efficiency and high performance. Our range of underground connectors is compatible with heat shrink, cold applied, resin and gel sealing technologies. The range includes:

• Mechanical shear bolt connectors and terminal lugs: Made of aluminium alloy and/or copper, our range-taking connectors and terminal lugs incorporate shear bolt technology. This helps generate optimal contact force to minimise connection resistance.
• Compression connectors and terminal lugs: Our Utilux and SIMEL ranges are available in aluminium, copper and bi-metallic versions. These products should be crimped with tooling that we also offer in our portfolio.
• Insulating Piercing Connectors (IPC): We offer ‘main to main’ and ‘main to service’ one-phase or Ring type IPCs. These connectors can be used on low-voltage live lines. Using insulation-piercing technology, they don't require stripping the cable insulation. Our connectors are suitable for all types of conductors, including sector or round shapes, and for solid or stranded aluminium and copper conductors.

Overhead connections must withstand harsh environments without compromising network performance. Our range for overhead networks includes:

• Power system clamps: Our suspension and anchoring clamps are range-taking and offer resistance to corrosion and temperature variations.
• AMPACT wedge connectors: This range is for cables up to 3000 MCM on distribution, substation and transmission applications up to 500 kV. AMPACT tap connectors use the action of a metal wedge to secure the two conductors to be connected at opposing ends of the C-clamp. Their elastic force prevents creepage, compensating for the expansion and contraction of the assembly during thermal cycling.
• AMPACT in-line switches (ILD): These combine the reliability of copper blade components and a double string of polymeric insulators with the AMPACT dead-end yoke assembly. The result is an in-line switch for distribution lines from 15 kV up to 69 kV.
• Insulating Piercing Connectors (IPC): Our IPCs provide electrical connections for aluminium and copper stranded conductors. Their metallic blades, embedded in moulded plastic and surrounded with a sealing compound, ensure electrical contact in low-voltage overhead distribution networks. A single torque-control nut draws the two parts of the connector together and shears off once the teeth have pierced the insulation and contacted the conductor strands.
• Removable circuit breakers: These provide a breakpoint on low voltage insulated lines up to 60A max.

Proper grounding and bonding are critical to the effective operation of all electrified systems: power, telecommunications, and data communications. We offer:

• Grounding connectors: This category of connectors is used for earthing applications for equipment grounds, system grounds, ground electrode systems, as well as lightning protection grounding applications. We recently added AMP Weld exothermically welded connections to our existing product line which includes WRENCH-LOK, SHEAR-LOK, and AMPACT copper tap connectors. Our AMP Weld exothermic welding process fuses conductors together to produce permanent grounding connections. 
• Link boxes: Our link boxes offer a sealed and dry environment for high voltage cable sheath earthing connections. They reduce voltages and circulating currents.

To help you install our electrical connectors, we have a range of hand tools suitable for mechanical, compression and wedge connectors.
