Selecting machines for 11kV to 800kV composite insulators requires more than checking voltage class. Machine capacity is also driven by product length, mechanical load, fitting design, shed profile and required tests.
Buyers should use the voltage range as a starting filter, then confirm the real mechanical and dimensional requirements with production and testing equipment suppliers.
Voltage is only one parameter
Two products with similar voltage class may require different length, creepage distance, fittings and mechanical strength.
Machine selection should therefore use complete drawings or clear product specifications.
Match production equipment to product geometry
Molding machines, crimping machines and marking equipment must handle the longest planned sample and the largest fitting.
For production equipment options, review the insulator production machine category.
Match testing equipment to load and standard
Mechanical testers should match tensile, bending, cantilever or torsion requirements.
Electrical equipment should match voltage level, test space and safety requirements.
Leave room for future sizes
If future products will be longer or higher load, discuss expansion early.
Upgrading later may require different fixtures, machine frame or workshop layout.
Buyer checklist
- Voltage class
- Maximum product length
- Rated mechanical load
- Fitting drawings
- Required test standards
FAQ
Can one line cover the full 11kV to 800kV range?
It depends on product type, length and capacity. Some equipment can cover broad ranges, while molds and fixtures remain product-specific.
What documents should buyers provide?
Provide drawings, voltage class, load rating, standard and target capacity.
Next step: send Contune your product range, drawings, standards, target capacity and destination country through the contact page. The engineering team can recommend a practical machine package before quotation.
