Properties of G10 plastic composite sheet insulation material for switchgear
Switchgear is a general term, mainly including high and low voltage switchgear, switch box, circuit breakers and other distribution equipment. Switchgear development history is also relatively long, from the beginning of 10KV oil switch to today's 1100KV SF6 and SF8, its insulation materials also develop from phenolic paper laminated material, phenolic cotton laminated material, epoxy phenolic laminated glass cloth board (tube, rod) material to vacuum pressure epoxy glass cloth impregnated tube (plate), vacuum pressure impregnated epoxy glass yarn rod and other vacuum pressure epoxy products. G10 fiberglass board is now one of the materials selected by switchgear manufacturers.
G10 plastic sheet, usually called G10 epoxy board, G10 insulation board, G10 glass fiber board, the flame retardant performance is slightly weaker than FR4 epoxy board. G10 composite is made of imported electronic grade alkali-free glass fiber cloth soaked with imported epoxy resin, adding the corresponding imported flame retardant, adhesives and other additives by hot pressing. Good mechanical properties and dielectric properties at high temperature, good processing properties and insulation properties are important performance for G10 glass fiber board used in circuit breakers, switchgear and other switching equipment. The water absorption of G10 glass fiber board is less than or equal to 0.8%, and the thermal stress is good. The working temperature of G10 sheet can reach 288℃ in a short time without delamination.
At present, the specifications of ZTelec Group G10 fiberglass board are 1020mm*1220mm/1020mm*2040mm/1220*2040mm/1220*2440mm. The thickness and tolerance can be processed and produced according to the needs of customers. A variety of colors can be selected and a variety of processing methods can be provided.
