Industry Application
Distribution And Sub-transmission Networks
Distribution networks buy insulators by the tens of thousands and maintain them with small crews over long routes. What matters is unit cost, inspection speed and having one coupling size in the store room.
Pain Points
What Goes Wrong In This Sector
- Line patrols cannot tell a good porcelain disc from a punctured one by eye
- Mixed insulator types across a network multiply spares inventory
- Outage windows for live testing are hard to schedule on feeders
- Cost per disc dominates when the order is 50000 units
Requirements
What Buyers Here Actually Need
- Light discs at 40 kN and 70 kN that a two-person crew can handle
- Visible self-destruction so a ground patrol finds the faulty unit
- One standardised ball and socket coupling across the network
- Predictable 15 to 35 day lead times for rolling replacement programmes

How We Deliver
Support Across The Project Cycle
From selection through manufacture to on-site guidance, handled by the same engineering team.
Pre-Sales Technical Consultation
Selection starts from your line conditions, not from our catalogue.
Customized Design And Manufacturing
When the standard disc does not fit the site, we develop one that does.
Production And Quality Assurance
Defective shells are removed in our furnace, not on your tower.
Logistics And Global Delivery
Export packing and documentation handled as part of the order, not as an afterthought.

Pradex Engineering Partnership And Factory Audit
Mr Andrey from Pradex visited the Jinhao plant in Linyi for a technical review covering the glass shell forming line, the toughening and thermal shock stations, the cementing line and the finished goods inspection area.
Answers
Distribution And Sub-transmission Networks Questions
Which discs suit distribution work?
The U40B at 40 kN and 1.8 kg, and the U70BS at 70 kN and 3.6 kg. Both are standard profile for clean and mild pollution.
How do glass insulators reduce inspection cost?
Internal defects cause visible self-destruction, so a defective unit is found by a ground patrol rather than by live testing that needs an outage window.
Can you support rolling replacement programmes?
Yes. Lead time is normally 15 to 35 days after order confirmation and deposit, and we support long-term framework supply as well as one-off orders.
Tell Us About The Route
Voltage, mechanical load, pollution class and quantity. We will size the string and confirm what we can deliver and when.
