Product Features and Performance
Reliable long term insulation with excellent tracking resistance and voltage withstanding performance, meets operating requirements of medium low voltage insulators.
Balanced mechanical strength and impact resistance withstand assembly stress and external vibration for insulator structural parts.
HDT ≥200 ℃ prevents softening deformation under temperature rise, securing stability of insulating structures.
UL94-V1 self extinguishing performance satisfies flame safety requirements for electrical insulator components.
Low water absorption minimizes insulation performance degradation under humid conditions; high Barcol hardness delivers dust abrasion resistance.
Good flow ability realizes one shot forming of curved & special shaped insulators, suitable for mass production. In house BMC lines guarantee stable bulk supply with formula tuning available.
Applications
Low-voltage post insulators, line insulators, switchgear insulating support insulators, transformer insulating cores, busbar insulators, insulating support columns for electrical equipment, and various medium & low voltage electrical insulating supports.
