Manufacturer of low voltage insulators and busbar systems in polyester material

From over 50 years we’ve been in business as qualified manufacturer of low voltage insulators and bus bar systems and supply the most important companies.
Our mark ERIB, the oldest one in Europe, is recognized all over the world as a quality guarantee.
All our insulators are indeed made of polyester material reinforced with fiberglass “BMC RF 3/20”, supplied by the company POLMIX SRL, UL certified UL 94 V-0 file nr. E205214 and classified HL2 according to the EN45545-2.
We continue to manufacture insulators by compression moulding in order to optimise the high-level electrical and mechanical performances of polyester material.
For this reason our insulators endure, without any inconveniences, particularly heavy stresses like mechanical shock, heat-strokes, electric discharges, which generally cause damages when using other material.
Their resistance is long term guaranteed, our insulators indeed keep intact their characteristics for many years.
We have one of the widest range of sizes to meet the different needs of our customers and a wharehouse always well stocked to guarantee the best delivery times.

Our series type DB/P and our vertical rodholders PSB are tested for shortcircuit resistance according to EN61439-2.
