Application scope: To prevent short circuit faults caused by small animals such as mice and snakes, and to prevent corrosion of the busbar by chemicals such as acid, alkali, and salt; To prevent maintenance personnel from accidentally entering the live gap and causing accidental injury, adapt to the development trend of miniaturization of switchgear, and solve the problem of phase to phase insulation in bus ducts.

Compared to ordinary heat shrink tubing, flame-retardant heat shrink tubing is adjusted in terms of formula composition during production, and various production factors are appropriately blended. At the same time, flame retardants are added to give it flame retardant properties. The so-called flame retardant refers to the prevention of combustion, which means that our heat shrink tubing cannot burn even under high heating conditions. Even after heating for a long time, igniting the heat shrink tubing will extinguish the flame at the same time due to the effect of the flame retardant.
