The braided heat shrink tubing combines the properties of classic heat shrink tubing and a durable textile braid. This piece has an internal diameter of 20 mm and a length of 30 m, making it suitable for very thick power cables, wide wire bundles, and thick conductors. When heated with hot air, the braid shrinks at a ratio of 2:1 and tightly encases the protected conductor. The braided surface is flexible, highly abrasion-resistant, and according to the manufacturer, helps to reduce cable noise. The thirty-metre length is sufficient for extensive installations and regular work with very thick cables and wide bundles in service.
Shrinking begins at approximately 80 °C and full shrinkage is achieved around 120 °C. A hot air gun is sufficient for heating, and the manufacturer also mentions the possibility of using a lighter. Once cooled, the tubing forms a continuous textile layer that protects the insulation of the conductors from mechanical damage, abrasion, and heat. The material is self-extinguishing with a flammability rating of VW-1 and withstands operating temperatures from −40 to +150 °C, making it suitable for cabling in cars or in electrical appliances that heat up during operation. The tubing can be used to protect joints, terminate cables, extend conductors, or bundle several thin cables into one neat bundle.

When selecting the size, follow the diameter of the cable. The manufacturer recommends choosing tubing approximately 3 mm larger than the diameter of the protected conductor. For flat cables or bundles with a rectangular cross-section, the required diameter is calculated by multiplying the sum of the width and height by two, dividing by 3.14, and adding 3 mm. The tubing is supplied in one piece, so you can cut it to the exact lengths you need before shrinking. Slide it onto the cable before connecting the connectors, then move it to the desired position and evenly heat it along its entire length.
The braided heat shrink tubing with a diameter of 20 mm is a practical addition for anyone repairing, modifying, or newly installing electrical wiring. The length of 30 m covers extensive installations, wiring of distribution boards, and repeated modifications of very thick cables and wide wire bundles in service. The textile surface protects the conductors from abrasion, the heat from the hot air gun quickly shrinks it, resulting in neatly and securely stored cabling. Thanks to its self-extinguishing properties and resistance up to +150 °C, it can be used in electronics, automation, electrical appliances, and in cars.
