Literature Describes Canted Coil Springs for High Current Transmission & Distribution

A new technical guide published by Bal Seal Engineering, Inc. provides high current transmission and distribution equipment designers with a detailed look at how springs can solve tough connecting and conducting challenges.

The eight-page guide, titled “Connecting and Conducting Solutions for High Current Power Transmission & Distribution,” describes the use of the company’s compact, precision-engineered Bal Seal Canted Coil Spring® as an electrical contact element for switchgears, circuit breakers, current transformers, cable accessories and other power management equipment. The guide presents data on the spring’s current-carrying capacity (in amps), as well as mechanical and electrical properties such as thermal conductivity (in W/m-K°), resistivity (in µΩ-cm) and hardness (HV). A full-page illustration depicts the springs at their approximate size.

The Bal Seal Canted Coil Spring®, a solution already at work in critical power transmission and distribution applications worldwide, offers OEMs the ability to reduce costs, eliminate maintenance issues and improve equipment performance. Available in a broad range of coil heights, wire materials and plating types, the spring maintains a nearly constant force over a broad compression range, compensating for angular misalignment, surface irregularities and even temperature changes without significant deviation from its initial force. Each coil works independently, maintaining contact with the mating surface and ensuring maximum conductivity. The versatile component’s locking, latching and holding properties also allow designers to meet very specific insertion and breakaway force requirements.

The new guide can be downloaded free of charge from the company’s online technical library at http://www.balseal.com/tmb-13-power-transmission-distribution. Requests for free printed copies can be e-mailed to [email protected].
