Excelitas Technologies Corp.
Higher-voltage and Higher-power Supplies require more complex design solutions. The heat to be dissipated and installation infrastructure, plus choice of insulation system in a HVPS are driven by the output voltage and output power which ultimately dictates packaging. Typical insulation systems are based on air, dielectric oil, epoxy, RTV Silicone and even Sulfur Hexafluoride (SF6). The method of cooling is a factor as well, the choices often coming down to air, water or oil, depending on the platform design requirements. These applications require Excelitas' detailed understanding to help choose the best design solution.

PBOF -
Teledyne Marine ODI
Pressure Balanced, Oil-Filled (PBOF) hose assemblies from Teledyne ODI are designed and qualified to accepted industry standards. The double-walled hose design incorporates inner and outer elastomeric barriers with fiber reinforcements to withstand the demands of long performance life requirements in deep ocean interconnect and distribution applications. The hose is filled with non-conductive silicone oil, which acts as a pressure compensator and dielectric. The electrical and/or optical conductors are loosely housed within the oil-filled assembly.

B-1020-C -
ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.
