The sun and the wind generate clean energy; power cables transmit it everywhere, safely, efficiently and sustainably.
In the renewable energy sector, the efficiency and reliability of wind and solar power plants depend crucially on the quality of the electrical connection systems. Every connection is a critical point: it must ensure electrical continuity, mechanical integrity and resistance to environmental stresses throughout the plant’s entire lifecycle.
In a solar or wind farm, thousands of conductors—from module-side DC cables to medium-voltage AC connections—form the network through which energy is generated, transferred and fed into the grid.
Thanks to its established expertise in the generation, transmission and distribution of energy, CEMBRE offers solutions designed to meet the most complex technical requirements of solar and wind power plants.
- Terminals and cable lugs capable of maintaining a stable crimp over time, even on tinned or flexible conductors.
- DC connections between modules, strings and inverters, where it is essential to ensure extremely low contact losses and resistance to thermal cycling.
- AC connections on the inverter side and in MV substations, subject to vibrations, climatic variations and high currents.
- Connectors and terminals resistant to corrosion in marine and offshore environments.
- Robust and reliable connection systems to withstand vibrations and cyclic torsion in the turbine tower.
- MV connections subject to high thermal and mechanical stress, with enhanced insulation requirements.
- Connection systems in power cabinets and substations for distribution within the energy grid.
- Connectors and terminals for energy storage stations (BESS), where contact resistance stability is critical for system safety.
- Sleeve connectors for branch connections and earthing systems for the overall safety of installations.
In renewable energy systems, failures at connection points represent a constant danger. The connectors installed in solar inverters or in turbine nacelles are exposed to various stress factors, including weathering, high DC voltage in solar systems, high AC current in the grid, and constant vibrations and stresses (particularly in wind turbines).
To meet the demands of the energy transition, Cembre offers complete systems for the installation of cable lugs and terminals, designed to ensure joints and terminations of high quality, fully UL-certifiable, guaranteeing reliable performance and long-lasting durability.
Mechanical, hydraulic and battery-powered tools: Versatile solutions for fast and safe crimping operations.
Wide range of crimping dies: for consistently effective crimping.
Hydraulic pumps and heads: ideal for high-intensity work and connections on large-diameter cables.
CABLE PROTECTION AND FASTENING
Secure electrical connections for an uninterrupted power supply
Cable glands are essential components for securing, sealing and protecting cables in wind and solar power plants, where strength and reliability must be guaranteed even in extreme environmental conditions. Cembre’s solutions are certified to IP68 protection, ensuring sealing, durability and safety over time.
- Plastic cable glands: Resistant to UV, weathering and corrosion.
- Nickel-plated brass cable glands: Maximum mechanical strength for harsh environments.
- Extended clamping cable glands (plastic / brass): Ideal for installing large-diameter cables, such as those used in wind turbines, without taking up excessive space.
- Plastic and brass accessories: Adapters, reducers, locknuts and plugs to support cable gland installation.
The cable marking and identification process is essential to ensure renewable energy systems are tidy, safe and compliant with regulations, as well as simplifying inspection and long-term maintenance activities.
Cembre offers a complete marking system based on thermal transfer printing, integrated with the GeniusPro software, to produce permanent, high-quality tags and labels in various materials, including:
- PVC
- Polyolefin
- Halogen-free polycarbonate
