The first batch of ELKAOIL oil submersible cable with aluminium alloy conductors is undergoing pilot field tests at Novomet-Perm (Novomet Group). The volume of the batch produced by Bogoslovsk Cable Plant (BKZ) is 30 km.
The cable for submersible electric pumps is intended to supply energy to electric motors of an oil extraction unit. The ELKAOIL cable uses heat-resistant and corrosion-resistant aluminium alloy (TAC) cores, which ensures reliable and durable contact at junctions. The cable is designed for a rated voltage of 3.3 and 4.0 kV with an operating frequency range of 35-200 Hz. The long-term permissible temperature of core heating is 120°C.
The ELKAOIL cable differs from copper analogues in its lighter weight and more attractive price. Its advantages include no negative effect of copper ions on polymer insulation. In addition, aluminium alloy cores have increased resistance to hydrogen sulphide dissolved in the well fluid.
FACT SHEET
Bogoslovsky Cable Plant produces self-supporting insulated cables and flexible aluminium and oil submersible cables. Using unique aluminium alloys in production, including those containing rare-earth metals, makes it possible to maintain and improve the physical properties of the products, as well as reduce their costs by 30-40% compared to copper-based analogues.
As part of the strategy to convert inefficient facilities, Oleg Deripaska, founder of UC RUSAL, suggested that new aluminium processing facilities be developed at Bogoslovsky Aluminium Smelter (BAZ) to produce competitive, high-value-added products, expand employment opportunities and create jobs.
In November 2016, UC RUSAL and ELKA-Cable Group signed a joint venture agreement to produce cable and conductor products. Financing of the project, in which each of the partners owns 50% of the equity, is being carried out on a parity basis. The total investment amounts to RUB 765 mln.
