Prysmian Group We have developed and put into use a line of cable products for the mining industry. This is the result of fruitful cooperation between the company and the giants of the industry, identification of the fundamental needs of the industry and successful time testing of all technologies used. The use of innovative materials and advanced engineering solutions has formed a reliable, durable and functional product. The cable for open and underground excavation is characterized by increased mechanical resistance and is ready for operation in the most extreme conditions.
