The Plio-Super 2.5 white insulating sleeve from Ses-Sterling is a flexible protective element for electrical wiring and cables in installations. It provides mechanical and electrical insulation as well as protection against external influences such as dust, moisture, or mechanical stress. The sleeve is used in electrical installations, building technology, and industrial applications where a reliable cable protection solution is required. It is packaged in a length of 50 metres and is suitable for use in indoor and outdoor environments, provided the ambient conditions comply with the specified operating conditions.

Insulating sleeve

The Plio-Super 2.5 is a thermoplastic protective sleeve made from polypropylene (PP) or a similar plastic. It is pulled over cables or wires to protect them from mechanical damage, contamination, or electrical interference. The designation 2.5 refers to the inner diameter of the sleeve in millimetres, designed to accommodate cables with a corresponding diameter. The white colour ensures good visibility and is standard in many installations.

Applications

The sleeve is intended for use in electrical installations, particularly in building technology, for wiring sockets, switches, lights, or in industrial electrical installations. It can be used in dry and damp rooms as well as in areas with moderate mechanical stress. The temperature resistance ranges from -20 °C to +90 °C, making it suitable for a wide range of indoor applications. Outdoor use is possible, provided ambient conditions remain within the specified temperature limits and there is no direct sunlight or aggressive chemicals present.

Functions and equipment in detail

The sleeve offers high flexibility, allowing it to be easily pulled over cables and installed in tight spaces or at complex routing points. The smooth surface facilitates cable insertion and reduces the formation of dirt or deposits. The material composition ensures good chemical resistance against water, oil, and other common industrial chemicals. The packaging unit includes 50 metres of sleeve, sufficient for larger installations and designed to streamline work processes.

Technology explained simply

The protective sleeve functions as a passive protective cover, not performing any active function such as power supply or signal transmission. It serves exclusively for mechanical and electrical insulation. The material selection ensures high resistance to mechanical stress, such as pressure or friction, and prevents short circuits. The temperature resistance from -20 to +90 °C allows use in various environments, from cool storage rooms to warm machine rooms. The weight of 4.7 g per metre is low, facilitating handling and installation.

Compatibility and accessories

The sleeve is compatible with cables and wires with a diameter up to 2.5 mm. It can be combined with other products from the Plio-Super series to ensure a consistent protection solution in an installation. Use with other protection systems such as cable sleeve clamps, ferrules, or mounting elements is possible, but not included in this item.

Installation and mounting

Installation is performed by simply inserting the cable into the sleeve, with the material's flexibility enabling easy routing. It is recommended to unroll the sleeve before installation to avoid knots or creases. Routing can be done in open or concealed installations, with the ends of the sleeve being cut or sealed with appropriate end caps after installation to ensure a clean and safe finish.

Operational advantages

The protective sleeve provides reliable and durable insulation, extending the service life of the cables inside. The easy handling and low weight simplify installation, especially for longer routing distances. The white colour allows for clear identification and is specified as the standard colour for electrical protective sleeves in many standards and regulations. The thermal resistance ensures safe operation even under varying ambient conditions.
