Colombia is undergoing various transformations driven by the arrival of new models and sustained sales growth. Other factors such as charging infrastructure, technological gaps, and the need for consumer education are shaping the course of electromobility in Colombia. Firms like BYD occupy a dominant position in public transport, extending to other important cities such as Cali, Medellin, Manizales, and Pereira and municipalities with growing interest in electrical alternatives. BYD’s strategy includes the incorporation of more than 2,000 new electric buses in the mass transit system. The units will include advanced technologies such as blade batteries, designed to extend the autonomy and lifespan of the buses. Additionally, the Chinese brand JAC has made a strong commitment to local electromobility with the launch of three new electric models. Double-arming bolts are crucial in electrical distribution systems, including electric vehicle charging infrastructure.
Double-arming bolts provide structural stability, safety, and durability for overhead power lines and utility poles. A double arming bolt is a heavy-duty fastener used to secure crossarms, support insulators and conductors, and withstand mechanical stress. Its features include a dual-threaded design, made of galvanized steel, and use in medium- and high-voltage power lines feeding EV charging stations. Double-arming bolts reinforce overhead power lines that feed electricity to charging hubs. The bolts ensure minimal power disruptions, which is crucial for highway fast-charging corridors. They also prevent pole failures due to cable weight or extreme weather. Double-arming bolts help maintain safe clearances between power lines and nearby structures. They also reduce the risk of electrical fires caused by loose cables. The future can witness smart grid integration, advanced materials, and standardization for the bolts.
Double-arming bolts in Colombian EV and charging infrastructure
The Colombian electric shift is mainly fueled by record-high EV sales, public fleet electrification, and fast-charging infrastructure. A double-arming bolt ensures the reliability of overhead and structural support systems. It is crucial in the mounting, securing, and stabilization of power hardware in EV charging setups and grid connections across the country. It is a threaded fastener used in utility pole assemblies to attach two crossarms on opposite sides of a utility pole. They provide mechanical support for overhead power lines and anchor essential components like transformers, insulators, and charging supply conductors. Here are the key functions of double-arming bolts in EV and charging infrastructure.

- Secure mounting for overhead EV feeder lines—EV charging hubs in remote or semi-urban areas rely on overhead electrical distribution from grid feeders. Double-arming bolts anchor crossarms that hold conductors supplying chargers, prevent pole rotation, and allow double-sided line routing.
- Support for transformer mounts and charging panels—pole-mounted step-down transformers or distribution panels convert medium voltage into usable EV charging voltages. Double-arming bolts secure crossarms that hold heavy electrical equipment, distribute load evenly on poles, and help accommodate multi-circuit installations to support high-output stations.
- Grid resilience in EV-heavy areas—double-arming bolts reinforce poles to withstand wind, vibration, and dynamic loads. They also enable redundant circuits and extend the lifespan of EV-related power infrastructure.
- Modular expansion for future charging corridors—modular pole assemblies using double-arming bolts allow efficient support for solar-integrated charging stations.
Challenge of charging infrastructure in Colombia
Colombia is experiencing one of South America’s fastest transitions to electric mobility. However, the momentum faces challenges such as the charging infrastructure that is still underdeveloped and unevenly distributed. There are various efforts to address these challenges. These include a national electric mobility strategy to encourage public-private partnerships for fast charger rollouts. The following are the challenges facing charging infrastructure in Colombia.

- Charger-to-vehicle imbalance—Colombia has one public charger for every 33 electric vehicles, which is far below international best practices. EV owners face long queues or need to rely on slow home chargers that limit long-distance travel.
- Fragmented charging standards—the market currently uses many connector types that cause compatibility and interoperability issues. EV drivers face confusion and limited charger access while infrastructure providers hesitate to invest without clear guidelines.
- High cost of fast-charging infrastructure—installing DC fast chargers is expensive due to grid upgrades needed for higher load capacity, import taxes, and construction costs in rugged terrain. Charging stations remain level 2, which takes 6-8 hours for a full charge, which is impractical for logistics fleets.
- Weak integration with renewable energy—few EV chargers integrate with solar or wind energy systems. Solar-powered stations exist in pilot projects but are not yet mainstream or grid-tied at scale.
