The company started producing armored cables in 1991, and armored cables are one of the company's leading products. Magnesium oxide powder is pressed into magnesium oxide columns and filled between the conductor and the outer tube of the armored cable as an insulating material for the armored cable. The quality of magnesium oxide columns is a decisive factor affecting the quality of armored cables. At present, the quality of domestic magnesium oxide columns is unstable, and the high-temperature insulation performance cannot meet specific requirements. The price and cost of foreign magnesium oxide columns are high, the production delivery cycle is long, and the response is not timely. In order to stabilize product quality, reduce production costs, and improve market competitiveness, the company has established an annual production of 10 million high-temperature insulating magnesium oxide (columns) project.
