Overview of Fiberglass Uncoated Sleeve Heat Treated Flame Retardant Uncoated Fiberglass Sleeving Used in Transformer

Fiberglass Uncoated Sleeve Heat Treated Flame Retardant Uncoated Fiberglass Sleeving Used in Transformer is the primary insulation device outside the transformer box, used to ensure the insulation of the transformer winding wires. It consists of multiple parts, including the central insulated capacitor core, external insulated upper and lower porcelain components, etc. According to the voltage level, there are various forms of bushings, such as pure ceramic, oil-filled bushings, and capacitor bushings. During the operation of a transformer, the insulation sleeve through which the winding leads is one of its current-carrying components, which needs to withstand the load current and short-circuit current.

5 FAQs of Fiberglass Uncoated Sleeve Heat Treated Flame Retardant Uncoated Fiberglass Sleeving Used in Transformer

What is this sleeving made from?
This sleeving uses pure fiberglass threads. No coatings or finishes are added. The material stays bare fiberglass. This gives good electrical insulation.

How hot can it get?
It handles very high heat. The sleeving withstands temperatures up to 550°C (1022°F). This heat tolerance comes from a special heat treatment process. The treatment makes the glass fibers tougher.

Does it resist fire?
Yes, it resists fire well. The heat treatment also makes it flame retardant. It won’t easily catch fire. It won’t keep burning if exposed to a flame. This is vital for transformer safety.

Where is it used inside transformers?
It protects important wires. You find it on lead wires, tap changer connections, and coil connections. It shields these wires from heat and electrical shorts. It prevents wires from touching each other or the transformer core.

Why pick uncoated fiberglass?
Uncoated sleeving has key benefits. It offers excellent dielectric strength for insulation. It breathes well, letting heat escape. It stays flexible after heat exposure. It resists many chemicals and solvents. It often costs less than coated options. It works reliably in demanding transformer environments.
