We manufacture a range of coils that are suitable for use on applications where a potentially explosive atmosphere exists. The designs are approved by either BASEEFA or ISSeP, depending on the design. They all use encapsulation for explosion protection and are available with a choice of cable types. SY and SWA cable is most frequently used. The cable is encapsulated into the coil so cable type and length must be specified at the time of order. When connected to our control units, they produce a HT voltage of approximately 8000V. A few versions of the encapsulated coil are detailed below.
