Periodic inspection of protective high voltage insulation equipment:

Prior to use, gloves made of insulating material must be tested. Periodic testing is performed every 6 months, and our team comes to you or transports the equipment to the company’s premises. Also, we determine the quality and safety of electrical insulating rubber footwear for staff working in electrical plants every 12 months, and we check the equipment in the warehouse every 2 years.


The purpose of installing an electrical insulation mat is to protect people and devices from high voltage breakouts. Our team tests its functionality every 12 months to maintain the safety of your employees and work equipment, while hollow and foam-filled insulating pipes are periodically tested every 24 months.


In addition to the above, we perform inspection and control of manipulative poles, voltage indicators, insulation boards and stands. We perform the test with a test voltage of up to 50 kV, at your location or in the premises of our company.
