Engineered for extreme Nordic conditions, our top-tier waterproof wire taps and circular connectors ensure flawless power and signal transmission across diverse local industries.
Sweden is globally recognized for its robust engineering, unyielding commitment to sustainability, and advanced technological infrastructure. From the bustling automotive innovation hubs in Gothenburg to the expansive green energy grids spanning across the freezing landscapes of Norrland, the demand for highly reliable, durable, and waterproof electrical components is at an all-time high. In such a dynamic industrial ecosystem, standard electrical connectors simply cannot survive the harsh Nordic climates.
Waterproof wire taps and heavy-duty circular connectors are indispensable in this landscape. Sweden experiences long, freezing winters, heavy snowfall, and significant coastal moisture from the Baltic Sea and the North Sea. These environmental factors pose a constant threat to electrical integrity, risking moisture ingress, short circuits, and rapid corrosion. By utilizing IP67 and IP68 rated waterproof wire taps, Swedish contractors, manufacturers, and engineers can ensure that power distribution, signal transmission, and data communication remain secure, completely moisture-free, and operational under the most severe conditions.
As a leading manufacturer and supplier, we are bridging the gap between cutting-edge Chinese manufacturing and precise Swedish engineering requirements. Shandong Longli Electronics Co., Ltd. is 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 state-of-the-art R&D centers in Linyi, Xi’an, and Jinan. It possesses comprehensive third-party service capabilities, including rigorous testing and inspection services, with prestigious certifications such as CMA and CNAS. By bringing these unparalleled quality control standards to the Swedish market, we guarantee that every waterproof wire tap supplied meets the stringent safety and environmental regulations expected in Scandinavia, including CE, RoHS, and REACH compliance.
Our mission is to empower global industries, particularly the fast-evolving sectors in Sweden, with indestructible connectivity. 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. In Sweden, this translates directly to supporting the nation's transition to a fossil-free welfare state by providing the backbone for smart infrastructure.
How our advanced connectivity solutions are powering the future of Scandinavia.
Sweden is a global pioneer in e-mobility, home to automotive giants like Volvo Cars, Polestar, and heavy-duty vehicle manufacturer Scania. The rapid shift towards electric vehicles (EVs) requires flawless high-voltage connections. Our waterproof wire taps and new energy vehicle connectors are heavily utilized in battery management systems (BMS), charging infrastructure, and complex vehicular wiring harnesses. They provide the necessary insulation and moisture resistance to prevent electrical degradation during harsh Swedish winters.
With an ambitious goal to achieve 100% renewable electricity production by 2040, Sweden is heavily investing in wind power (such as the massive Markbygden Wind Farm in northern Sweden) and hydropower. Wind turbines face extreme weather, including UV radiation, freezing rain, and constant mechanical vibrations. Our smart grid connectors and waterproof taps are engineered with PA66 nylon housings and silicone gel seals to endure these exact conditions, ensuring uninterrupted power flow to the Swedish national grid.
The Swedish mining industry, particularly the LKAB iron ore mine in Kiruna—the largest and most modern underground iron ore mine in the world—demands equipment that can survive the most brutal environments. Underground moisture, abrasive dust, and intense mechanical stress easily destroy standard wiring. Our specialized mining connectors and heavy-duty bayonet waterproof circular connectors provide superior ingress protection and mechanical locking, keeping automated mining equipment safely connected.
Given Sweden's extensive coastline along the Baltic Sea and the Kattegat, maritime operations are a cornerstone of the economy. Saltwater corrosion is the enemy of electrical systems. Our marine-grade waterproof wire taps feature gold-plated contacts and anti-corrosive shells, making them the ideal choice for Swedish shipbuilders, offshore platforms, and port automation systems in Gothenburg and Malmö.
To continuously serve high-tech markets like Sweden, relentless R&D is required. The company has undertaken more than 60 research projects, including the Torch Program of the Ministry of Science and Technology, provincial major science and technology projects, and provincial key R&D programs. It has received 25 scientific and technological awards, including provincial science and technology awards and provincial SME technological progress awards.
Over 20 achievements have passed provincial appraisals, with two reaching international advanced levels and twelve achieving domestic leading levels. This innovation engine guarantees that Swedish procurement managers receive products equipped with the latest advancements in material science and electrical engineering.

As Sweden continues to develop smart city initiatives in Stockholm and Malmö, the reliance on Internet of Things (IoT) sensors, automated street lighting, and intelligent traffic management systems will grow exponentially. Every single one of these outdoor sensors requires a fail-safe power and data connection. Our waterproof wire taps provide the quick, reliable, and weather-resistant splicing needed by municipal installers. By choosing our advanced circular connectors, Swedish cities can future-proof their infrastructure, reducing maintenance costs and ensuring that smart city grids remain online regardless of the weather.
