The United Kingdom's industrial landscape is undergoing a significant transformation, driven by the "Green Industrial Revolution" and the rapid expansion of offshore wind energy in the North Sea. As a leading Waterproof Cable Joint Factory & Supplier, we recognize that the UK market demands high-specification components capable of withstanding the harsh, saline environments of the British coastline and the rigorous safety standards of the London Underground.
From the bustling tech hubs in Cambridge to the heavy industrial zones in the West Midlands, the demand for IP68-rated waterproof circular connectors has surged. These components are no longer just simple accessories; they are critical failure-prevention points in the UK’s national infrastructure, including smart grids, 5G telecommunications towers, and the burgeoning electric vehicle (EV) charging network across England, Scotland, and Wales.
It is also recognized as a national-level "Key Little Giant" enterprise (specialized, refined, unique, and innovative), a provincial-level Gazelle Enterprise, a Hidden Champion, and a Manufacturing Single Champion in Shandong Province. The company operates R&D centers in Linyi, Xi’an, and Jinan. It possesses comprehensive third-party service capabilities, including testing and inspection services, with certifications such as CMA and CNAS.
With the UK being a global leader in offshore wind power, our waterproof cable joints are engineered to resist salt spray corrosion and high-pressure submersion. These are vital for connecting turbines in the Dogger Bank Wind Farm and other North Sea projects.
The UK's rail network, including HS2 and the upgrade of the Great Western Main Line, requires high-reliability connectors. Our FQN and FQ series provide the vibration resistance and moisture sealing necessary for modern rail signaling and rolling stock.
In Aberdeen’s oil and gas sector and the developing blue economy, waterproof circular connectors are essential for ROVs (Remotely Operated Vehicles) and subsea sensors, ensuring data integrity at extreme depths.
From Manchester to Birmingham, the deployment of IoT sensors for smart city management relies on weatherproof joints to protect sensitive electronics from the British weather, ensuring 24/7 operational uptime.
The company primarily offers seven major categories of products, including military connectors, smart grid connectors, new energy vehicle connectors, railway locomotive connectors, mining connectors, petroleum connectors, and marine connectors, encompassing over 130 series and thousands of specifications.
These products are widely used in aviation, aerospace, military electronic equipment, as well as various sectors of the national economy such as power grids, new energy, railways, telecommunications, petroleum, and coal mining.
Over 20 achievements have passed provincial appraisals, with two reaching international advanced levels and twelve achieving domestic leading levels.
Awarded Science and Technology Progress, Patent Star Enterprise, and Famous Trademark. Numerous products listed in the National Torch Program.
Over 10 senior engineers and 100 R&D professionals. Regional R&D centers and 12 technical departments focused on next-gen connectivity.
Certified to ISO9001:2015 & IATF16949:2016. Equipped with advanced testing labs and complete quality processes for the UK market.
Products exported to more than 20 countries. Long-term stable partnerships with military, grid and new energy clients worldwide.
As the UK pushes towards its Net Zero goals, the technology behind waterproof cable joints is evolving. We are seeing a shift towards miniaturization—where high power must be delivered through smaller, more compact connectors to fit into sleek consumer EV chargers and compact urban sensors.
Furthermore, the integration of Smart Monitoring within cable joints is an emerging trend. Future connectors may include sensors to detect moisture ingress or heat fluctuations before a failure occurs, providing real-time data to maintenance teams in London or Edinburgh. As a forward-thinking supplier, Shandong Longli Electronics is at the forefront of this AI-integrated hardware revolution, ensuring our UK partners stay ahead of the curve.
