Colour	Yellow/Green

The Pliofine BX-VJ-03 480 heat shrink tube from Ses-Sterling is a product specifically developed for use in electrical and installation technology. With a length of 1.22 metres and a yellow/green colour, it is used for marking and protective covering of cables and wires. The yellow/green colour is standardised in electrical engineering as the protective conductor colour and is therefore particularly used for marking earthing conductors. The heat shrink tube is made of a thermoplastic material that shrinks when heated to approximately 100 °C to 120 °C, forming a tight, dense covering around the underlying wires. The shrink ratio of 3:1, common in the industry, means that the tube has an unshrunk diameter three times larger than the diameter after shrinking. This allows flexible adaptation to different cable diameters within the specified range.

Heat shrink tube is the central product described here. It is a type of shrink tubing that is reduced to a smaller diameter by applying heat (e.g. with a hot air blower). The yellow/green colour is not only visually striking but also complies with international standards for protective conductors, making it especially suitable for applications in electrical safety. The length of 1.22 metres allows processing of longer cable sections or multiple cables in a single operation, thereby increasing installation efficiency. The shrink ratio of 3:1 is a technical parameter describing the flexibility of the tube when adapting to different cable diameters. This value is typical for heat shrink tubes of this product class and ensures a secure and tight fit after shrinking.

Applications include electrical installation, particularly in buildings, industrial plants, and machine wiring. The heat shrink tube is used to protect, mark, or insulate cables. The yellow/green colour primarily serves to clearly identify protective conductors, supporting compliance with safety regulations and standards such as DIN VDE 0100 or IEC 60364. In practice, the tube is often applied to cables used in earthing systems, enclosures, or electrical device wiring. Using a heat shrink tube on protective conductors increases visibility and reduces the risk of incorrect connections.

Functions and features in detail include thermal shrinkability, activated by applying heat. The material reacts at temperatures from approximately 100 °C, with the optimal shrink temperature ranging between 100 °C and 120 °C. After shrinking, the tube forms a dense, shape-stable sheath that protects against mechanical stress, moisture, and external influences. The surface is smooth, enabling easy installation and a clean visual appearance of the wiring. The packaging unit includes a single piece, as specified by the manufacturer. The indication 1 piece refers to the sales and delivery quantity, typically supplied as a single item.

Technology explained simply means that the heat shrink tube is made of a thermoplastic polymer that changes shape when heated. The material is in an expanded state before processing, defined by the shrink ratio of 3:1. When heated, the material contracts and conforms to the underlying cable. Shrinking occurs evenly, preventing gaps or folds. The use of a hot air blower or a dedicated shrinking device is required to reach the necessary temperature. Shrinking time is short, usually within seconds, depending on cable diameter and heat source.

Compatibility and accessories refer to use with cables and wires within the shrink ratio of 3:1. The heat shrink tube is not specific to certain cable types and can be universally applied to cables whose diameter matches the shrink ratio. Compatibility with other products in the Pliofine range is ensured, as the product line features standardised properties.

Installation and mounting are carried out by placing the heat shrink tube over the cable to be protected. The tube is positioned to cover the desired length. Heat is then applied using a hot air blower or similar device until the tube shrinks and forms a tight sheath. Temperature should not exceed 120 °C to avoid damaging the material. Processing is simple and does not require special skills, although proper handling is necessary to ensure even shrinking.

The operational advantages lie in easy handling, high visibility due to the yellow/green colour, and secure mechanical and electrical insulation. The heat shrink tube protects underlying wires from mechanical damage, moisture, and contamination. The tight fit after shrinking prevents dust or moisture ingress, increasing cable lifespan. The colour coding simplifies identification of protective conductors, improving safety during maintenance and repair work. The product is universally applicable and can be used across various industries and applications without requiring special adaptations.
