Strukton’s Power business unit in Sweden has received an order for eleven LTC 3.0 systems.

LTC 3.0 is the third generation of Strukton’s patented solution for line testing and transient‑free energisation of overhead contact lines. The system contributes to a more reliable power supply for railway overhead line systems by reducing switching operations that could lead to short circuits and unnecessary relay protection trips.

The new LTC systems will be installed in various switching stations along the Bothnia Line in Sweden.

Over the past 18 years, Strukton has delivered more than 200 LTC systems to railway power supply installations in Sweden and Norway.

Frequently asked questions

Find answers to frequently asked questions here.

Why is expanding the electricity grid essential for Europe’s energy transition?

Expanding the electricity grid is crucial to support increasing demand from renewable energy, electric mobility, gas‑free homes and growing data‑center capacity. A larger and stronger grid ensures reliability, prevents congestion and enables the seamless integration of solar, wind and other sustainable energy sources.

What civil engineering works are needed to build and upgrade energy networks?

Modern energy networks rely on extensive civil engineering works, including the construction of high‑voltage substations, transmission‑line foundations, access roads, cable routes and site preparation for electrical stations. These works form the physical backbone that allows grid operators to expand capacity safely and efficiently.

How do smart grid solutions help optimise existing electricity infrastructure?

Smart grid solutions improve network performance by capturing, storing and reusing energy more intelligently. Technologies such as mobile or modular substations, regenerative systems and energy‑storage units help reduce peak loads, increase efficiency and make better use of the existing grid — reducing both costs and environmental impact. An example is Strukton’s Energy Bank (OV energiebank).

What types of power‑supply systems are used to provide reliable energy for rail transport?

Reliable rail transport depends on dedicated AC and DC power‑supply systems, including converter stations, feeder stations, traction‑power substations and mobile energy‑supply units. These systems enable stable and resilient power delivery for heavy rail, metro, tram and light‑rail networks across Europe.

How do converter stations and feeder stations support modern rail operations?

Converter stations and feeder stations ensure that rail networks receive the correct voltage and frequency, even as traffic intensifies or train weights increase. Mobile and permanent installations provide flexibility, strengthen weak network sections and support international rail corridors with varying technical requirements.
