Working on Your Next Light Rail Project? Here’s What OEMs Need to Know

By Scott Anderson on 27 March, 2019

The global light rail industry is forecasted to reach $4.97 billion by 2026, growing at an annual rate of 9.8%. While Europe continues to maintain the highest market growth, the recent rise in light rail passengers across major U.S. cities has led to approvals for light rail extension projects throughout the country — expecting to drive market growth even further. Light rail vehicles produced by companies like Bombardier, Siemens, Kawasaki, Hitachi, Alstom, Ansaldo, and others are expanding across the nation due to advancements in areas like noise reduction, comfort and safety.

Trust But Verify: Process and Product Validation

By George Allman on 06 February, 2019

Trust But Verify Main Image

In cable assemblies and wire harnesses, there are hundreds and often thousands of opportunities for defects per assembly. Therefore, it is imperative that a manufacturer takes rigorous steps to mitigate the risk of incurring those defects. Multiple process controls must be deployed to ensure that a wire assembly is produced that meets or exceeds the customer’s requirements. Many of these measures are taken before the components are even built. Revision-controlled quality requirements---specified on prints and in workmanship standards---must be understood. Operators must be trained and must demonstrate this understanding. As an assembly is produced, a predetermined regimen of tests and other validations are employed, both by operators and technicians. These validations, depending on the project, can include mechanical, electrical, and environmental tests. Each of these stages in the quality assurance process ultimately ensures that the product meets or exceeds the customer specifications.

Wire Bundle Management: Holding it All Together

By George Allman on 21 November, 2018

Making sure wire bundles are adequately secured or contained is an important step in creating a quality product, even after the necessary electrical or environmental protection has been applied. It is imperative that a wire assembly be secured adequately, and it is also crucial that the bundle fits well within the physical space allotted. This is where various wire bundle management techniques come into play. Wires can be held together using heat shrinkable tubing, lacing, stitching, tie wraps, metal bands, or braided coverings. The style and material used to secure the assembly helps it achieve the best performance possible.

Molding Materials: One Over Another

By George Allman on 14 November, 2018

Molding protects the connectors of a wire assembly from a variety of potential harmful influences. These include environmental factors such as water and chemical damage, as well as abrasion and other physical damage in service. Using the best material for the job also ensures the best possible adhesion for the components, yielding reliability and longevity of the end product. The choice of molding material used is directly related to the desired function and level of performance, and utilizing the best materials in the industry---such as urethanes , silicones, and epoxies---ensures the highest quality of assemblies according to client needs.

Understanding Insulation Materials

By George Allman on 10 October, 2018

Insulation materials provide wiring harnesses with a layer of necessary protection in a variety of ways, depending on the specific requirements the product must meet. Insulation helps protect the product mechanically, electrically, or environmentally, meeting particular needs according to the product’s application. Additionally, a variety of materials used in wiring harness insulation ensure the various functions of cable harnesses are carried out in the best way possible using the best materials for the job.
