Ses-Sterling 07390031003 Pliofine B-EX 3200 (1.22 m) green shrink tube 2:1 content_copy

The Pliofine B-EX 3200 (1.22m) green shrink tube from Ses-Sterling is a protective material specifically developed for use in explosive atmospheres. It serves for mechanical and electrical insulation of cables, wires, and electrical connections, particularly in installations that must comply with the requirements of the Explosion Protection Regulation (Ex Regulation). The shrink tube reduces in size when heated, fitting tightly around the protected conductors and forming a dense, protective sheath. The green color serves as optical identification and is established in industry as a standard color for specific protective functions.

Applications

The Pliofine B-EX 3200 shrink tube is intended for use in explosive atmospheres, particularly in Zone 1 and Zone 2 according to explosion protection standards. It is commonly used in the chemical industry, oil and gas sector, and process engineering, where the risk of explosion from flammable gases or vapors exists. Use in such environments requires materials that do not act as ignition sources and securely protect electrical insulation. The shrink tube provides reliable mechanical and electrical insulation that remains stable even under mechanical stress and environmental influences.

Functions and Features in Detail

The shrink tube has a shrink ratio of 2:1, meaning it reduces to half its original outer diameter when heated. This enables a tight fit around the protected conductors and ensures a dense, airtight covering. The green color is not only visually identifiable but also serves as a marking for specific application areas, particularly in industrial electrical installations. The length of the shrink tube is 1.22 meters, providing sufficient material for multiple applications or longer sections.

Technology Explained Simply

The shrink tube is made of a thermoplastic material that shrinks when heated (e.g., with a heat gun) and tightly conforms to the conductors beneath. The shrinkage occurs evenly, preventing gaps or loose areas that could serve as entry points for moisture, dust, or other environmental influences. The green color is part of the material and remains intact even after shrinking. Installation involves sliding the tube over the conductors to be protected, heating it, and allowing it to cool, thereby stabilizing the shape.

Compatibility and Accessories

The Pliofine B-EX 3200 shrink tube is designed for use with electrical wires and cables installed in explosive atmospheres. It is compatible with standard cables and wires commonly used in industry. Installation requires no additional tools or materials, except for a heating device to warm the tube.

Installation and Mounting

Mounting is done by sliding the shrink tube over the conductors to be protected, ensuring sufficient clearance for shrinkage. The tube is then heated using a heat gun or other suitable heating device until it fully contracts. The temperature should be chosen to ensure even shrinkage without burning the tube. After cooling, the insulation is stable and durable. Installation is typically performed by skilled personnel familiar with explosion protection requirements.

Operational Advantages

The shrink tube provides reliable, dense insulation that remains stable even under mechanical stress and in humid or dusty environments. The green color facilitates visual identification and compliance with safety regulations. Use in explosive atmospheres reduces the risk of ignition sources and increases plant safety. The simple installation and long service life make the shrink tube a practical tool in industrial electrical installations.
