About Nikara

Nikara Trading was established in 1990 by a group of electrical and business specialists. The company’s business department studied the monopolies in different parts of Iran’s electrical industry since the beginning of the activity and proposed some solution for cost reduction of the products needed in this section through field observations and managers’ personal experiences.
With the endeavors of the Foreign Trade Department, the company has been able to sign long-term contracts with four reputable eastern (Chinese) companies including Biduk, Gold Control, MWW, and Reign Power.
Experiments and experiences of customers of Nikara Trading during these years confirm quality, efficiency and highly reasonable prices of the products of these four brands.
Products of the companies could win quality international standards and they were exported throughout the world.
