Optimising connections
09 June 2016
High-end hi-fi equipment specialist, Naim Audio, has installed a Carbolite GP oven to provide precisely controlled heat-treatment procedures on the cables used in its systems.

The Carbolite GP330B oven allows up to 60 metres of cable to be processed at a time in order to cure the insulation and make it more supple and durable. The procedure typically involves heating the oven at a pre-set rate, holding at temperature for several hours and then cooling to ambient.
The controller fitted allows up to 20 segments to be pre-set as ramp, step or dwell and also enables operators to store the most frequently used programs.
Overall oven construction is designed to provide long-term durability in a production environment. The internal chamber is manufactured from polished 430-grade stainless steel and provides a powerful horizontal airflow to optimise temperature uniformity.
Low-thermal-mass insulation minimises heat loss. To enable Naim to operate the oven from a 240V supply, Carbolite fitted lower-power elements than usual.
