Award's Submersible Electric
Set-Screw Connector - Highlights
Connection degradation in electrical distribution networks is
currently an important problem. Various elements (oxidizing, galvanic corrosion,
fretting and thermal dilatation) contribute to the degradation, often resulting in the
premature failing of the connection.
Electrical connectors' designs have evolved very
little in the last 20 years. Our innovative connector (1) (patent pending)
replaces a wide range of connectors currently available on the market, including
aluminum set-screw (2) and copper bus bar models (3). Our connector is rated for
600v, up to 750 amps, and will enable standardization of products by eliminating
bus bar connectors (also simplifying installation by eliminating the extensive
hardware required). Our connector is truly in a class by itself, offering
genuine improvement to electrical connections, that we are confident will
revolutionize the industry.
Fits any cables sizes from 3-0 to 750 KcMil (4).
Reduced number of components (from 31 to 13 for the 6 cavities model)
Increased connection efficiency
Screw-type connectors currently available on the market use
screws that apply pressure on concentrated single points, thereby inducing
permanent deformation and reducing the integrity of the cable and the quality of
the contact (5-6-7). Bus bar-type connector require the use of an adaptor that
is compressed with cumbersome hydraulic equipment. Our connector benefits from a
metallic shoe that evenly distributes the pressure applied by the screw (8-9). The
resulting improved contact reduces electric resistivity of the connector, thus
reducing heat generation. Because less heat is produced, the connector can be
used for higher voltages applications.
Installation is faster and greatly simplified, as the cable
fits into the guide and is then perfectly fitted in the chamber.
The connector is totally enclosed in rubber to ensure
complete water tightness. Rubber is bounded to the metal, which i) individually
seals each chamber, ii) reduces water infiltration, and iii) prohibits water
migration to adjacent chambers. This is an important feature, as water is sucked
by electrical cables. If water comes from a cable, it can be transmitted to
other cables via the connector.
Connectors currently available on the market all have some
exposed metallic parts. Because of this, security protection (screen,
isolated tools) is required for the operator when working on assembling the
connector under charge. Our connector is designed in such a way that no metallic
part is openly exposed at anytime. Electrical shock and electric spark hazards
are thus eliminated. This puts our connector in a class by itself, as there are
no security apparatus required. Finally, the use of plastic blots eliminates
requirement of a cap to protect the bolt.
