Common Mistakes When Building a Composite Insulator Production Line

Building a composite insulator production line is a technical project. Common mistakes include unclear product range, incomplete testing capability, poor layout and underestimating tooling.

A better approach is to plan production, testing and commissioning together from the beginning.

Starting without product definition

Equipment selection should start from voltage class, product type, length, load and capacity.

Without this information, quotations become generic and risky.

Ignoring testing equipment

A factory that can produce but cannot test may struggle with customer acceptance.

Testing machines should be included in the first project scope.

Underestimating tooling and fixtures

Molds, dies and fixtures can determine product quality and setup efficiency.

They should not be treated as minor accessories.

Poor layout and installation planning

Long samples, high-load testers and molding equipment require space, power and safe handling.

Buyer checklist

  • Product range
  • Testing matrix
  • Tooling scope
  • Workshop layout
  • Training plan
