Composite insulator core rod material - fiberglass

Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the alkali content of the glass, can be divided into alkali-free glass fiber (sodium oxide 0% to 2%, belonging to aluminum Borosilicate glass), medium alkali glass fiber (8% to 12% sodium oxide, sodium or calcium silicate glass containing boron or boron) and high alkali glass fiber (more than 13% sodium oxide, sodium calcium) Silicate glass).
