PSD70E High Voltage Glass Insulator

PSD70E Glass Insulator is a cap-and-pin suspension glass insulator featuring a double-shed (double-skirt) profile with an extended creepage distance. It is designed for insulation and mechanical fastening of conductors on overhead power transmission lines and in distribution units of power plants and substations with AC voltages exceeding 1000 V. and the PSD70E insulator is ideally suited for operation in areas with heavy environmental pollution (industrial zones, coastal areas, and agricultural regions). Our Nooa Electric glass insulator complies with the requirements of GOST.

PSD-70E Glass Suspension Insulator

The PSD70E glass insulator is a suspension disc-type insulator with an extended leakage path (double-shed design), intended for the insulation and support of conductors on overhead power transmission lines and in the switchgear of AC power plants and substations operating at voltages exceeding 1000 V.

Thanks to its double-shed profile, the PSD70E insulator is ideally suited for use in areas with high pollution levels (such as industrial zones, coastal regions, and agricultural areas).


PSD-70E Glass Suspension Insulator

Application:
The PSD-70E insulator is used for the insulating suspension of conductors and lightning protection cables on:
- Overhead power transmission lines with voltages of 6–500 kV
- Outdoor switchyards of high-voltage substations
- Areas with high levels of atmospheric pollution

Frequently Asked Questions (FAQ)

1. What does the "PSD70E" designation mean?
The model designation is decoded as follows:
P — Suspension type;
S — Glass insulation material;
D — Double-shed / double-skirt profile ;
70 — Minimum mechanical failing load in kilonewtons (70 kN);
E — Modification / design iteration index.

2. What is the main difference between PSD70E and PS70E insulators?
The PSD70E insulator features a double-shed design (two outer skirts), which provides a significantly longer creepage distance compared to the standard aerodynamic or standard-profile PS70E insulator. PSD70E is specifically engineered for high-pollution environments (pollution severity levels III–V).

3. Which climate conditions are PSD70E insulators suitable for?
The insulators are manufactured in the UHL1 climatic version according to GOST 15150. This means they are designed for open-air outdoor operation in temperate and cold climate zones, withstanding operating temperatures from -60°C to +45°C.

4. Which standards do your insulators comply with?
Our PSD70E glass insulators fully comply with GOST 6490-2017 ("Line suspension disc insulators") as well as the international standard IEC 60383. Type test reports and certificates of conformity are available upon request.

5. What is the creepage distance of PSD70E and why is it important?
The creepage distance of the PSD70E insulator is at least 410 mm (depending on the specific drawing). A longer creepage distance enhances the insulator's resistance to leakage currents and electrical flashovers during rain, fog, frost, or heavy surface contamination.

6. How are PSD70E insulators packaged for shipment?
Insulators are assembled into strings (typically 6–7 units) or packed into sturdy wooden crates/pallets, reinforced with steel strapping and protective film. The packaging guarantees safe sea, rail, and road transport.
