Protecting Electrical Rooms From Mining Dust

April 13, 2020

SPCC, Southern Peru Copper Corporation, used Roxtec cable seals when extending the Toquepala copper ore mine on the Andes mountain range. It was far better than cable glands.

SPCC had realized that neither traditional cable glands nor foam were enough to protect the equipment in the harsh mining environment. The cable glands did not prevent the dust from passing through and pollute the electrical rooms, and the foam was too easily detached. Their suppliers, mine contractors Siemens and CSE, solved the problem by installing a variety of Roxtec seals in seven new electrical rooms.

“We have managed to standardize with large Roxtec seals in order to simplify the purchase of frames. We only have to focus on the adaptable sealing modules,” states SPCC.
