Insulation Dog Bones
Glass pultrusion stays
Top Glass manufactures DOG BONE profiles made in composite material. Our products are reinforced with fibreglass and they represent one of the pultruded profiles made by Top Glass.
Our pultruded profiles are indispensable in the production of electrical devices such as dry-type transformers, electric motors and coils.
First of all their main strength is their optimal electrical insulation ability.
This makes them ideal for use in the aforementioned systems involving strong electrical current.
Glass pultrusion stays, including dog bones, vertical bars, cylindrical batten, coattail batten, stay plate etc., are a type of profile produced by a pultrusion process using an alkali-free glass fiber-impregnated thermosetting resin.
It has high mechanical strength, excellent electrical properties, and flame retardancy, orrosion resistance, arc resistance and other advantages. It is mainly used for the ventilation cooling between dry transformers and the use of reactors and wave traps.
