Insulator Selection and String Design
Getting from a line specification to a bill of material without a second revision.
Six Steps From Enquiry To Delivery
Each step has an owner and an output, so nothing waits on a decision nobody made.
Line data
Voltage, span, conductor, tower window and the pollution class along the route.
Load class
Pick the mechanical failing load class - 40, 70, 100, 120, 160, 210, 240, 300 or 550 kN.
Shed profile
Standard, anti-fog, double shed or open aerodynamic, based on the pollution and icing you actually have.
Creepage check
Confirm the total creepage distance of the string against the specified mm per kV.
Coupling
Match the ball and socket size, 16, 20 or 24 mm, to the fittings already specified.
Documents
Drawing, type test report and routine test record issued before production starts.

Straight answers to the questions buyers ask before a first order.
How long does the insulator selection and string design route take?
It depends on the scope, but type confirmation and drawing approval are usually the long pole. Send the line data first and the rest moves quickly.
Do you charge for drawings or samples?
Drawings for listed types are issued free with a live enquiry. Sample and freight cost is agreed case by case before dispatch.
Who will I be dealing with?
The export sales desk at Jiangxi Huayao Electric Co., Ltd., reachable on WhatsApp at +86-15870073965 and by email at [email protected], Monday to Friday 9:00 to 18:00 China time.
Can you work to our drawing?
Yes. Send the drawing or a sample and we will confirm what can be held before tooling starts.
Start With The Line Data
Voltage, span, conductor, pollution class and the specified load class. That is enough for a first type list and a price.
