2. Question two:
How can we get different size of rubber insulators?
Answer: by different size of molds, if the insulators with same shed diameters, same rod diameters, just creeping distance is different, you can choose one mold base but with exchange molds inserts to get different length insulators, super saving money solution.
3.Question three:
How many components of one insulators?
Answer: Silicone rubber insulators is belongs to composite insulators, includes three parts: silicone rubber external layer, FRP rod and metal fittings. Compared with Porcelain insulators, rubber insulators manufacturing process is more easier and more environmentally friendly. For the FRP rod and fittings, normally you can find enough existed suppliers in China by alibaba or exhibitions or our recommendations. For molding equipment, solid rubber molding machine or liquid rubber molding machine, molds, water chiller, rod pre-heating device. If condition or technology accumulation is allowed, rubber mixing machines, lab testing devices, rod and fitting clamping machine can be invested. For newcomers, there will be a professional insulators manufacturing company to provide the technical and certificated supports to help customers to pass the all kinds of state grid permit approval.
