Splice Shunts for Conductor Repair
The conductor is the largest single component of the power delivery system. It is the delivery pathway from generation to the user. With vast exposure to the environment, damage is bound to occur that will impact efficient transfer of energy. To effectively and safety repair this critical system component, Preformed Line Products offers materials that are easy to install, perform like the conductor and provide worker safety.
Preformed Line Products’ splice shunts are an effective solution for the repair of aging and deteriorating compression and automatic splices, and dead-ends. It can also be used as part of a solution to upgrade existing transmission and distribution lines without the need to re-conductor. Among splice shunt features:
• Helical design mimics conductor’s mechanical characteristics under tension;
• Single-component, outer-layer assembly;
• Easily installed with hot sticks, eliminating the requirement of a line outage;
• Restores 100 percent of the electrical and mechanical integrity of the conductor;
• Will eliminate hot spots caused by existing electrical connections;
• No tools required; and
• Permits existing lines to be up rated.

Coax Stripper Helps Prevent Poor Connections that Lead to Video Reception Problems
More than 70 percent of video reception problems can be traced to a bad cable connection. Often 80k pounds (300kN) the culprit is a badly stripped length of cable. IDEAL is helping assure better connections by introducing its new 45-321 coax stripper designed to perform cleaner, faster 1/4 inch x 1/4 inch strips of RG-6/6 quad and RG-59 coax cables used in the transmission of cable television, satellite broadcasting and analog closed circuit television signals.
The stripper features a self-adjusting blade that instantly conforms to different diameter coax cables, resulting in higher accuracy at a lower overall cost of installation. The 45-321 has a spinner ring that orbits the full circumference of the cable to deliver faster stripping without compromising precision. The 45-321 is ergonomically shaped, lightweight and easy to maneuver in tight spaces. It is also compact in size so it fits easily inside a pocket or tool tote.

QCI Series Shearbolt Connectors Eliminate Need for Additional Tools
For utilities looking for a reliable alternative to compression connectors for medium voltage cables, 3M Electrical Markets Division introduces the Shearbolt Connectors, QCI Series.
The Shearbolt Connectors create a reliable, consistent connection using continuous shearing determined by contact force—not torque value. In addition, the bolt shears below the connector body because the bolt shears axially, not at a pre-defined shear point. This eliminates the need for filing and ensures the correct contact pressure. A friction plate on the bottom of the bolt prevents conductor damage while providing increased contact force.
Designed for American Wire Gauge conductors, the Shearbolt Connectors meet the requirements of the American National Standards Institute (ANSI) C119.4, Class 2. In fact, the connectors exceed the 40 percent pull-out force required for splices by the Institute of Electrical and Electronics Engineers- (IEEE-) 404.
The shearbolt connectors reduce installation time and errors by eliminating the need for crimp tools or dies and reducing installation error.

Cable Glands Feature Electroless Nickel Plating for High Corrosion Resistance
Appleton has upgraded the protective finish on its cable glands with new electroless nickel plating for high corrosion resistance in harsh industrial environments.
Due to its high hardness, electroless nickel plating enhances the life of cable glands exposed to severe service conditions. Parts undergoing electroless nickel plating will in many cases perform much like stainless steel.
In addition to corrosion resistance, advantages of the new finish include:
• Wear resistance to protect against galling,
• Uniformity of deposit regardless of geometries—extremely important for flameproof/explosionproof threads,
• Stable thickness control, and
• Nonmagnetic properties of high-phosphorus nickel alloy.
Appleton cable glands are used to attach ends of electrical cable to equipment in a variety of applications.
