Beida Group, based in Tianjin, China, is a professional manufacturer of medium-voltage power cables, and this type of cable is one of our core products. Leveraging a comprehensive product portfolio and extensive manufacturing experience, Beida Group's cables cover a wide range of applications, meeting the power transmission needs of various industries.
Medium-voltage power cables are critical components in power transmission systems, primarily used for the transfer and distribution of electrical energy. These cables have clearly defined voltage classifications, and Beida Group focuses on medium-voltage power cables in the 6–35kV range.
Cables in this voltage range are distinct from both low-voltage power cables (1kV and below) and high-voltage transmission lines. The 27.5kV medium-voltage power cable specifically designed for electrified railways is a unique specification offered by Beida Group, tailored to meet the high-voltage transmission requirements of specific applications.
Our medium-voltage power cables utilize high-quality conductor materials to ensure stable current transmission. The conductors have high conductivity, effectively reducing line losses and are suitable for long-term continuous operation.
Insulation performance is a core advantage of our medium-voltage cables. During the production process, relying on the 35kV high-speed CCV production line introduced from MAILLEFER in Finland, as well as multiple sets of domestically produced advanced extruders, and with advanced production and testing equipment, we ensure that the core performance of the cable meets the standards.
Some of our medium-voltage products use low-smoke, halogen-free sheath materials, which do not release harmful gases when burned, making them suitable for environmentally sensitive applications. Our flame-retardant and fire-resistant medium-voltage power cables can maintain power supply for a certain period in fire conditions, providing time for emergency response.
The protective performance is highly targeted: special protective designs against water, rodents, and termites allow the cables to adapt to complex scenarios such as underground installation and outdoor environments. Medium-voltage variable frequency cables have optimized anti-interference performance to meet the power supply requirements of variable frequency equipment.
Beida Group possesses flexible customization capabilities and can adjust the cable structure according to specific application requirements, meeting the personalized needs of different industries.
Urban power distribution networks are a core application scenario for medium-voltage power cables. Beida Group's 6-35kV medium-voltage cables are widely used in urban underground pipeline construction, replacing traditional overhead lines and reducing space occupation and environmental impact.
Industrial sector: Production workshops in industries such as metallurgy and petrochemicals require stable medium-voltage power supply to ensure the operation of large equipment. Our products can adapt to the stringent requirements of industrial environments.
Transportation infrastructure: The traction power supply system of electrified railways relies on 27.5kV medium-voltage power cables for energy transmission. As a professional supplier, Beida Group can also provide this specification of cable to meet the power supply needs of various railway construction projects.
Large buildings and public facilities: The power supply systems of commercial complexes and high-rise buildings require medium-voltage cables to distribute power between floors, ensuring the normal operation of various equipment.
Beida Group specializes in wires and cables, establishing a product structure encompassing high-voltage, low-voltage power cables, electrical equipment cables, and flexible mineral-insulated cables. Medium-voltage power cables, a crucial segment of this structure, cover multiple core categories across over 200 series.
The product range includes 6-35kV medium-voltage cables, medium-voltage variable frequency cables, and flame-retardant and fire-resistant medium-voltage cables, meeting the diverse needs of different applications.
We prioritize product quality control, overseeing every stage from raw material procurement to production and processing. All cables undergo rigorous testing before leaving the factory, ensuring that all performance indicators meet industry standards and providing users with reliable power supply guarantees.
Leveraging years of industry experience, Beida Group's Medium-Voltage Power Cables have served numerous industries, including power, metallurgy, petrochemicals, railways, and construction, becoming the preferred product for many projects.
