Insulation Protection Armor for High-voltage Equipment: Flame-retardant Silicone Rubber Self-fusing Tape

The safe operation of high-voltage equipment is inseparable from reliable insulation protection, and Volsun FST6030SI flame-retardant silicone rubber self-fusing tape is the "invisible armor" tailored for high-voltage scenarios. With the characteristics of "self-adhesive fusion and full-effect protection", it builds a reliable insulation barrier for exposed cable joints, copper bars and other components in substations, power plants and other places to ensure the safe and stable operation of equipment.

The core advantage of FST6030SI flame-retardant silicone rubber self-fusing tape lies in its excellent performance and convenient operation.

• It can maintain stable performance in a wide temperature range of -60℃~180℃, and can work normally regardless of severe cold or high temperature. At the same time, it also has excellent weather resistance, UV resistance, ozone resistance, and aging resistance. It is not easy to crack even after long-term outdoor use, and its service life far exceeds that of ordinary tapes.

  
  

• FST6030SI adopts self fusion technology, with no touch stickiness on the surface, no residue after peeling, and self-melts into one in a short time after winding to form a sealed waterproof layer. It can also be wound into any shape, tightly wrapping irregular parts such as cable connectors and busbars, without the need for special tools, and increasing installation efficiency by 50%.

  
  

• FST6030SI can maintain excellent insulation performance even in rainy or humid outdoor environments, meeting the stringent protection requirements of high-voltage equipment.

The technical indicators of FST6030SI flame-retardant silicone rubber self-fusing tape have been tested by a third party and fully meet the insulation protection standards for high-voltage equipment.

• Tensile strength ≥ 3.5MPa: strong tensile resistance, not easy to break when winding, and adapt to equipment vibration scenarios.

• Elongation at break ≥ 200%: high ductility, can tightly wrap special-shaped parts to ensure no gaps and improve insulation sealing.

• Bonding strength > 3.5N/cm: long-lasting self-adhesion, not easy to loosen after winding, ensuring long-term protection effect.

• Flame retardant grade V-0 (UL94): self-extinguishing and non-spreading in case of fire, meeting high flame retardant requirements such as substations, reducing fire risks.

• Breakdown strength ≥ 22kV/mm: high insulation, effective isolation of high voltage, suitable for insulation protection of 10kV and above equipment.

• Volume resistivity ≥ 1.3×10¹⁴Ω·m: stable insulation performance, no attenuation after long-term use, ensuring safe operation of equipment.

FST6030SI flame retardant silicone self-fusing tape is widely used in high-voltage scenarios such as substations, power plants, cable joints, new energy power stations, industrial control cabinets, etc.

• Substation/power plant: can be used for exposed parts of copper bars, switch cabinet busbar insulation, etc., flame-retardant V-0 grade and 22kV/mm breakdown strength, suitable for high-voltage environment, reduce short-circuit hazards, and reduce operation and maintenance costs.

• Cable joint protection: can be used for intermediate joints and terminal heads of power cables, self-adhesive fusion to form a sealing layer, waterproof and anti-fouling, -60℃~180℃ temperature resistance to adapt to outdoor temperature differences.

• Industrial control cabinet: can be used for exposed wires, wiring terminals, etc. in the cabinet, anti-corrosion and anti-fouling, flexible shaping to adapt to compact space, and improve the electrical safety level in the cabinet.

In short, Volsun provides a variety of specifications for FST6030SI flame retardant silicone self-fusing tape, and supports color and packaging customization to meet the needs of different customers.
