NTP Norway alternative suppliers
What are the alternatives to the European manufacturer NTP Norway Insulators?
The market is increasingly looking at alternative suppliers to NTP Products from Norway. Europe has only a handful of high-quality insulator producers, and most do not specialize in electrostatic precipitator (ESP) insulators. This niche was once filled by companies like IFO Ceramic in Sweden and EKS Sonneberg in Germany—both of which have recently closed. Many customers have lost their established porcelain insulators supply chains and are now searching for ESP support insulators, wall bushings, or shaft insulators for electrostatic precipitator.
ESPI Europe stands out as a reliable alternative to the Norway-based NTP Product Insulators.
ESPI Europe offers high-quality ESP insulators that meet European standards but comparing to NTP Norway at a more competitive price.
With limited production capacity across the EU, NTP Insulators, one of the region’s leading ESP insulators manufacturers, has shifted its focus toward post insulators, long-rod types. ESP insulators, typically ordered in low volumes or even as single pieces, are not a priority of NTP products.

Why choose ESPI Europe for ESP insulators?
ESPI offers ESP insulators comparable in quality and performance to those once provided by Norway producer NTP Insulators. In addition, we offer more affordable pricing and flexible delivery options. Our current annual capacity includes up to 20,000 conical support insulators. We highly focuse on ESP insulators in our company. We also supply popular designs in smaller-than-usual order volumes, or even from stock within just a few days.
ESPI offers In specific applications ESP insulators from high-alumina ceramics A95 with 95% Al2O3 content, which are temperature resistant up to 500°C.
How does ESPI ensure high ESP insulator quality?
Every batch produced by ESPI is thoroughly tested according to IEC 62155. This includes visual checks, dimensional verification, temperature cycle testing, DC withstand voltage tests (at high and room temperatures), and porosity check. On top of that, a 30-ton compression test is carried out as part of our standard procedure. All insulators go through these steps before being packed in plywood boxes compliant with international fumigation regulations for overseas shipping.
