A variable frequency drive (VFD) is a type of controller that varies the frequency of the signal and voltage to control motor speed. Other common names for VFD include variable speed drive, adjustable speed drive, constant torque drive, inverter drive, and pulse-width modulation (PWM) drive. But what is VFD cable, and why is it important? VFD cable is a specially designed power cable engineered to connect a variable frequency drive to a motor while withstanding the unique electrical stresses created by VFD systems. Unlike standard cable, VFD cable is designed to reduce electrical noise, manage voltage spikes and reflected waves, and help protect motors, drives, and connected equipment from premature failure.

Twenty years ago, Amphenol TPC Wire & Cable (ATPC) acquired Sanco, which would eventually become its Custom Build Shop (CBS). But the story of the CBS began long before the acquisition with a family willing to build something from the ground up. For Diane Anderson, Production Manager of Assembly at ATPC, the journey has been personal from the very beginning.

Una operación minera compró el mismo cable 24 veces en 24 meses. Nosotros hicimos las cuentas de lo que eso le costó — y de lo que dejó de costarle al cambiar de cable. 

Choosing the right welding cable size is critical for safety, performance, and preventing costly downtime. Welding cables carry high currents in demanding environments, and undersized or mismatched cable can overheat, lose efficiency, or fail prematurely.

The best industrial products rarely begin as ideas on a whiteboard. More often, they start with a challenge in the field — a cable that fails too quickly, an environment that existing products can't withstand, or a market need that hasn't been fully addressed. Successful innovation starts with identifying those opportunities and then combining customer insights with engineering expertise to create something better.

When utility companies deploy temporary power systems, mobile substations, or emergency backup infrastructure, the cable used in the process is only part of the equation. And the way those cables are transported, stored, deployed, and protected in the field can have a major impact on both operator safety and system reliability.

Sometimes, the most impactful innovations begin with a challenge. This is especially true when it comes to cable design. Whether it's fitting several lines into a compact composite cable or developing a solution that can withstand the harsh conditions inside a wind turbine, custom-engineered cables often solve problems that off-the-shelf products simply can't address.

Ampacity is crucial in industrial wiring to ensure safe and efficient electrical systems. Let’s explore what ampacity is, how it affects cable selection, and why it matters in industrial settings. 

Industrial cables don't last by accident. Long-term performance comes down to the right combination of material selection, cable construction, and engineering expertise with rigorous design standards. From conductor stranding and lay lengths to high-performance compounds and fluoropolymer insulation, every intentional design choice affects how a cable withstands flexing, abrasion, heat, chemicals, and constant motion in harsh industrial environments.

En una acería, una fundición o cerca de un horno, el cable no falla por mala suerte. La falla se debe a que se adquirió un cable que nunca fue diseñado para resistir el calor al que está expuesto. La buena noticia es que, para evitarlo, basta con saber leer un solo número en la ficha técnica —la temperatura máxima del conductor— y entender por qué casi ningún cable convencional resiste los entornos hostiles de su planta.

A medida que la tecnología de cables sigue evolucionando, las operaciones industriales exigen más de cada punto de conexión: mayor durabilidad, mejor flexibilidad, un diámetro de cable reducido y un rendimiento óptimo en entornos cada vez más saturados y exigentes.

Los avances en los materiales y el diseño del aislamiento han transformado lo que las soluciones de cableado modernas pueden lograr en aplicaciones de automatización, sistemas de enrollado (reeling) y energía. Por supuesto, se necesita un equipo de expertos para tomar esos materiales y transformarlos en nuevas soluciones revolucionarias.

Si en su planta los cables fallan, se queman o requieren mantenimiento constante, este caso real le va a doler… porque usted está pagando exactamente lo mismo que ellos pagaban. 

As cable technology continues to evolve, industrial operations demand more from every connection point: greater durability, improved flexibility, reduced cable diameter, and better performance in increasingly crowded and demanding environments. Advances in materials and insulation design have transformed what modern cable solutions can achieve across automation, reeling, and power applications. Of course, it takes a team of experts to take those materials and transform them into groundbreaking new solutions.

In harsh industrial environments, cable failure isn't just inconvenient — it can lead to costly downtime, safety risks, and frequent replacements. That's why thermoset jacketing has remained a core part of Amphenol TPC's cable design philosophy for decades. So, what exactly are thermosets? You may be familiar with everyday thermoplastics – things like PVC – that soften and melt when exposed to heat. Thermosets like vulcanized rubber and epoxy resins are the exact opposite in terms of what happens in the presence of heat. After they’re initially cured, they cannot be remelted. Able to withstand heat, abrasion, impact, oils, and demanding operating conditions, thermoset materials deliver the rugged durability industrial operations depend on.

Stopping production three times for the same failure isn't just bad luck... It’s a sign that your infrastructure is failing you. In the metallurgical sector, where the environment is a constant war, every minute of downtime is a massive capital leak.

A leading plant faced this exact scenario: 2,000 hours of accumulated downtime and an endless reactive maintenance cycle. The culprit behind this chaos? A conventional cable. Although it met "standard specifications," it simply wasn't designed to withstand molten metal or extreme heat. This triggered a domino effect that paralyzed the plant:
