Installation cable H07V-K (LGY) – reliability and safety in electrical installations

The H07V-K cable, commonly known as LGY, is a flexible single-core cable with a large cross-section, designed for demanding applications in electrical installations. This model with a cross-section of 35 mm² is distinguished by its high quality and durability, making it an ideal choice for both professional installers and end users. The cable is particularly recommended for making grounding connections and in lightning protection systems.

Construction and application

The H07V-K (LGY) cable consists of a multi-wire copper core (class 5 strand), providing high flexibility and resistance to mechanical damage. The PVC insulation guarantees safe use and protection against external conditions. The 35 mm² cross-section allows for the transmission of large currents, which is crucial in advanced electrical installations. The characteristic yellow-green color of the insulation clearly identifies the cable as intended for earth potential (PE), which increases safety.

This cable is widely used in professional power engineering and building construction. It is a standard for performing Main Grounding Buses (GSU) in buildings, connecting foundation grounds to the main distribution board, and in lightning protection systems (inside the building). Thanks to its flexibility, this cable is easy to install even in difficult conditions.

Key features and benefits

• Large core cross-section (35 mm²): enables the transmission of large currents, necessary in advanced electrical installations.
• Flexible construction: class 5 stranded core provides easy installation and resistance to bending.
• Durable PVC insulation: guarantees safe use and protection against external conditions.
• Yellow-green color: clear identification as an earthing conductor (PE), increasing the safety of the installation.
• Wide application: ideal for performing main grounds, equalization connections and lightning protection systems.
• Rated voltage 450/750 V: ensures compatibility with most standard electrical installations.
• Operating temperature range from -40°C to +70°C: allows the cable to be used in various environmental conditions.

Important: Installation of this cable, due to its large cross-section, requires the use of specialized tools – thick-walled crimp or ring terminals and a hydraulic crimper, to ensure a safe and durable connection and the ability to carry fault currents.
