Is the OL7 NON CONDUCTIVE thermoplastic hose safe for use near live transformers and high-voltage equipment during hydraulic system testing?

Yes. The OL7 NON CONDUCTIVE thermoplastic hose is designed specifically for use near transformers and medium- and high-voltage electrical installations and has been tested to demonstrate non-conductive behaviour: leakage current during testing is below 50 ÂµA at 246 kV/m for 5 minutes. It meets relevant standards (ANSI 92.2, SAE 100R7, ISO 3949-R7), which supports its suitability for hydraulic system testing in high-voltage environments. Operational limits to observe: ensure you use the correct hose diameter/assembly to match the working pressure range (70â230 bar), and respect the temperature limits (â40 Â°C to +100 Â°C; for water up to +70 Â°C). Always follow site safety procedures, periodic inspection and maintenance, and applicable local regulations when working near live transformers and high-voltage equipment.

Can the OL7 NON CONDUCTIVE thermoplastic hose withstand repeated flexing and pressure cycling near medium/high voltage equipment?

Yes. The OL7 NON CONDUCTIVE thermoplastic hose is specifically designed for use near transformers and medium/high voltage electrical installations and is nonâconductive (leakage <50 ÂµA at 246 kV/m for 5 min). Its construction-polyester inner layer, double polyester braid reinforcement and PU outer-provides flexibility and high mechanical strength. Working pressures range from 70 to 230 bar (by diameter) and the hose tolerates temperatures â40Â°C to +100Â°C (water up to +70Â°C), indicating suitability for repeated flexing and pressure cycling in hydraulic, fuel and waterâbased systems near medium/high voltage equipment when used within specified pressure, temperature and application limits and standards ANSI 92.2, SAE 100R7, ISO 3949âR7.

Does the OL7 NON CONDUCTIVE thermoplastic hose meet ANSI 92.2 and SAE 100R7 leakage limits during HV dielectric testing?

Yes. The OL7 NON CONDUCTIVE thermoplastic hose meets ANSI 92.2 and SAE 100R7 leakage limits during high-voltage dielectric (HV) testing. According to the product description, leakage measured during testing is less than 50 ÂµA at 246 kV/m for 5 minutes, which complies with the leakage thresholds specified in ANSI 92.2 and SAE 100R7 (and ISO 3949-R7) for non-conductive hydraulic hoses used near transformers and medium/high voltage installations.
