Product Description

This series of products is novel in design, easy to install, and is made of high-quality silicone rubber materials. It has excellent electrical, anti-leakage tracking and flesh-free flame retardant properties, and is extremely weather-resistant.
Excellent, high mechanical properties, hydrophobicity and hydrophobic migration, excellent high and low temperature resistance, and can be used continuously under -50C +150C conditions. When using, you only need to clean and tighten the bare conductors and buckle the sheathing tube. The installation is convenient and simple, saving labor and time. According to the difference of materials, it can be divided into three series: ordinary type, flame retardant type and ceramic fireproof and refractory type.

 

Features

1. On-site installation and disassembly are simple and fast, which can greatly shorten the maintenance and power outage time, and overcome the shortcomings of long manual wrapping time of the covering tape and long power outage;
2. There is no need to use a fire during installation and disassembly. It is softer and more resistant to bending than plastic open tubes. It is easy and convenient to install and disassemble. Operators do not need professional training, which overcomes the trouble of needing to use a fire when wrapping the covering tape;
3. It has a longer service life than plastic sheaths and coating tapes, up to more than 20-30 years. It is anti-aging and corrosion-resistant, has good corona resistance, high and low temperature resistance, excellent mechanical properties and electrical insulation properties, and low density. , good flame retardancy, halogen-free, and heavy metal-free. It is an upgraded product of covering tapes, plastic sheaths, and heat shrinkable materials.
4. Ensure the safe operation of electrical equipment, especially ceramic fireproof and refractory products that will not cause fire under overload and high temperature conditions.
