Flexible duct light grey SPIROFLEX SF 20 SF20_K30

Flexible cable protection under all conditions

The SPIROFLEX SF 20 corrugated conduit is a flexible electrical installation conduit made of polyvinyl chloride (PVC), designed to protect electrical cables in a variety of applications. It is characterized by high mechanical strength (320N/5cm) and flexibility, making installation easier even in difficult conditions. The light gray color facilitates identification and aesthetic matching to the surroundings.

The SPIROFLEX SF 20 conduit is reinforced with a spiral of rigid PVC, which ensures its resistance to mechanical loads and constant pressure. The smooth inner surface minimizes friction during cable pulling, and the flexibility allows for easy routing of installations in bends and tight spaces. It is an ideal solution for both professional installers and end-users who value durability and ease of installation.

Application and structural features

The conduit is used in surface, concealed, semi-concealed (screed) and wooden installations. The possibility of mounting in concrete expands its scope of use. Flame-retardant construction increases safety, and impact resistance class (medium - Class 3) provides protection against mechanical damage. Thanks to its flexibility, it is ideal for industrial systems, machine parks and anywhere where resistance to loads and pressure is required.

• Versatility: Suitable for installation in concrete, on wood, semi-concealed and surface-mounted.
• Durability: Reinforced spiral of rigid PVC ensures resistance to mechanical loads.
• Flexibility: Facilitates installation in difficult conditions and tight spaces.
• Safety: Flame-retardant construction increases safety.
• Easy installation: Smooth inner surface minimizes friction during cable pulling.
• Wide operating temperature range: From -5°C to 60°C allows the conduit to be used in various environmental conditions.

Operating parameters and compliance with standards

The SPIROFLEX SF 20 conduit has an outer diameter of 24.7 mm and an inner diameter of 20 mm. It is designed to operate in a temperature range from -5°C to 60°C. It does not have a coupling or markings of subsequent meters of the conduit, which simplifies the installation and use process. It should be noted that the product does not have UV resistance or is halogen-free. The use of PVC material guarantees good electrical insulation and moisture resistance.
