Effective surge protection for your project
Choose the highest level of protection and professional advice right from the component selection stage. High-voltage (HV) and medium-voltage (MV) surge arresters from a Polish manufacturer, as well as Arteche HV transformers and relays.
More than just a product
We help designers and engineers solve power protection challenges
We not only manufacture surge arresters but also provide consulting services on selecting modern power protection solutions. We offer comprehensive support to our partners – from the component selection stage through design, implementation, and commissioning, all the way to day-to-day operation.
How do we help?
We enhance safety in every sector of the power industry by selecting equipment with the appropriate specifications
For over 20 years, we have been supplying electrical equipment and solutions to many sectors of the power industry. At every stage, from equipment selection to implementation and commissioning, we support companies such as:
Distribution companies
in the modernization of power grids, substations, and renewable energy facilities.
Contractors in the energy sector
in selecting grid equipment with the appropriate specifications and ensuring its proper installation.
Design firms
by selecting the right equipment, providing documentation in CAD and 3D formats, developing technical documentation, selecting alternatives, optimizing budgets, and reducing project timelines.
Private investors in renewable energy
for whom the key issue is the effective and timely completion of investments, which is facilitated by Protektel's short project completion times.
Manufacturing companies
by providing budget-optimized solutions tailored to the technical conditions of the facility and its operational maintenance.
Public transportation
by providing modern solutions that improve passenger safety and comfort.
Energy producers
in both conventional and alternative energy sectors, to whom we offer surge protection tailored to the specific nature of their investments, as well as equipment for energy metering systems.
Who are we?
We met back in the 1990s. At the time, we were all working at ZWAR, which had evolved from the K. Szpotański and Company Electrical Appliance Factory, founded by Kazimierz Szpotański in November 1918. At ZWAR, each of us worked in a different field, gaining experience along our own career paths. However, we all felt that we could do our jobs even better. Fascinated by the achievements of Kazimierz Szpotański, in 2000 we started our own company, which began from scratch.

Our story
Business is built on people and a company's strength lies in its employees
We started out as a trading company, investing in research and development.
This allowed us to achieve our main goal—creating our own line of surge arresters. Today, we are a manufacturing and trading company that is constantly expanding its production capabilities.
For us, the greatest honor is not awards, but the trust of our customers, who rely on our solutions and expertise in their daily, responsible work.
Recognized in the market
Protektel once again among the “Business Gazelles”
For the fifth time in a row, we have been honored as a winner of the prestigious “Business Gazelles 2025” ranking, once again joining the ranks of dynamically growing Polish companies in the SME sector. Being awarded the title of Business Gazelle confirms Protektel's stable growth.

Surge protection for your project doesn't have to be a compromise
You don't have to choose between expensive components with specifications that exceed your needs and cheaper alternatives operating at the upper limits of their capabilities. 
Surge arresters custom-made for you and carefully selected Arteche components will perform exactly as you require. What are the benefits of using our power electronics devices?
- Wide operating parameter ranges – enabling a perfect match to the specifics of your project. This ensures everything works as it should.
- Robust construction – minimizes the risk of mechanical damage, both during transport and installation. You can be confident that the unit will function properly.
- Resistance to high temperatures and humidity – expands the range of applications and makes the products more resistant to failure, even in the event of unforeseen changes in operating conditions.
- Very high energy endurance – ensures a long service life. And for you, that means “peace of mind” for longer.
- Designed for operation in dirty environments – allows you to focus on the details of installation. You don’t have to waste time meticulously cleaning up the installation site.
- Easy installation – speeds up implementation and reduces costs. The investor in your project will certainly notice this.
- Maintenance-free operation – saves your employees’ time. Instead, you can assign them to other tasks.
We analyze the request for proposal
We resolve all issues
Often even at this stage we're already working on various challenges your project faces, such as potential power outages during subsequent work. We can also match a product from our lineup to competitors' specifications, so you don't have to do it yourself.
We provide technical support
From the very beginning of our collaboration, we offer advice on selecting products tailored to your needs. We provide detailed technical documentation, including CAD and 3D formats. If necessary, we'll prepare the appropriate technical documentation for you.
We customize our products
As a manufacturer of surge arresters, we can modify their parameters within certain limits to ensure you receive a product that best meets the technical requirements of your project.
We offer fixed sales prices
The prices of our components remain stable over a set period of time, regardless of supply continuity or market price increases. We stay in constant contact with you.

Frequently Asked Questions
Check out the answers to the most common questions asked by our partners.
Will you visit the project site?
Yes, if necessary, we'll be happy to conduct a site visit.
Will I receive the components I ordered despite global supply chain issues?
Yes, we have our own warehouse, so we can guarantee on-time delivery.
Will the prices you offer remain valid for a year or longer?
Prices are subject to change. However, if we can reach an agreement and sign a contract in advance that covers all important aspects (including terms of trade and payment), then yes. In that case, we'll reserve the materials needed for production for this project. We can manufacture the products in advance so they'll be ready for you.
Can you ship the goods today?
Shipping is possible provided that we receive the order information in advance (a few hours before 12:00 p.m. on the given day) and if the goods are already packed. If not, we'll do our best to ensure the order is shipped as soon as possible.
I just need some advice. Can I count on your support?
Of course – feel free to contact us!
