New Bus Duct Factory

Hi everyone.

We want to start a plant for manufacturing bus duct for medium and low voltages. Can anyone tell me where can I get the following useful information:-

1- what equipments are needed?

2- what are the best technology for the bus ducts? ( such as insulation, size)

2- if there is a website for a company that can help me establish this factory? or a joint venture that would like to work with us.

we worked in selling/ installing the bus ducts. and now we decided to manufacture them instead of buying them.
