Glass Standard Profile Suspension Insulators LXP-40 / U40B
40 kN Standard Profile Glass Disc for Light Distribution Strings
LXP-40 / U40B is the smallest toughened glass disc in the range: a 175 mm shed with 190 mm creepage, 110 mm spacing and an 11 mm coupling, rated at a 40 kN mechanical failing load. At 1.8 kg per unit it suits light distribution and guy applications where a full transmission-class disc would be oversized and expensive to handle.
Key Benefits
- 1.8 kg per unit, the lightest disc in the range to handle and ship
- 40 kN failing load with a 20 kN routine tension proof
- 11 mm coupling matched to light distribution hardware
- Toughened glass shell shows a punctured unit at a glance
Technical Features
- 175 mm shed, 110 mm spacing, 190 mm creepage
- 55 kV dry and 33 kV wet power-frequency withstand voltage
- 70 kV dry lightning impulse withstand voltage
- 130 kV puncture withstand voltage

Application Scenarios
- Light distribution line suspension and tension strings
- Temporary and construction power lines
- Rural feeder spans where loads are modest
Who It Is For
- Distribution utilities and rural electrification projects
- Contractors building temporary supply lines
- Wholesalers supplying small line hardware
Problems It Solves
- Over-specified transmission discs used on light distribution spans
- Shipping weight and cost on high-volume distribution orders
- Porcelain units that fail without any visible sign
How This Design Differs From the Alternatives
Compared With LXP-70 / U70BL
Smaller and lighter at 40 kN instead of 70 kN, with 190 mm rather than 320 mm creepage, for genuinely light spans.
Compared With ANSI 54-2 strain insulator
A disc that can be strung in series to build voltage withstand, where the strain unit is a single-piece guy component.
Specifying and Installing This Unit
- Confirm the span tension stays inside the 20 kN proof value
- Check that the 11 mm coupling matches your ball eye and socket clevis
- Use in clean or lightly polluted environments; step to a fog profile where salt or dust is present
- Handle in the supplied packing until assembly to avoid chipping the shed edge
Questions About This Product
Is 40 kN enough for a distribution line?
For most light distribution spans it is, but the string load calculation is what decides. Compare your maximum working tension with the 20 kN proof value and step up if it is close.
Can these be used in coastal areas?
The 190 mm creepage is a standard profile figure intended for clean to lightly polluted sites. For salt deposit choose a fog profile unit instead.
What is the minimum order quantity?
Order quantity is agreed per enquiry. Tell us the annual volume and delivery schedule and we will quote against it.
Do you mark each unit?
Yes. Type designation and production identification are marked on the unit so it can be traced back to its production lot.
How does this compare with a porcelain disc of the same rating?
The electrical ratings are set by the design, not the material. The practical difference is inspection: a punctured glass shell shatters and is visible, while a punctured porcelain unit usually is not.
