PI series

ERIM's PI Series insulated bushings provide a reliable solution for the safe passage of conductors through panels, enclosures and insulating barriers in low- and medium-voltage electrical equipment. Their design helps maintain the required insulation distances while ensuring a robust mechanical connection in power electronics equipment, electrical switchboards and power distribution systems.

Manufactured entirely by compression moulding, these bushings are made from BMC RF 3/20 glass fibre reinforced polyester, a material that provides an excellent balance of mechanical strength, dimensional stability and dielectric performance. The compound is self-extinguishing in accordance with UL 94 V-0 and classified HL2 according to the EN 45545-2 railway standard, demonstrating its suitability for demanding industrial environments.

The PI Series is UL certified under the following registrations:

• File No. E502533 – QEUY2/8 category for use below 1000 V
• File No. E502534 – DLAR2/8 category for use above 1000 V

Thanks to the compression moulding process, ERIM produces components with high resistance to mechanical stress, vibration and thermal variations, maintaining their insulating properties throughout extended service life. Their configuration with threaded studs at both ends allows safe, repeatable and reliable installation in a wide variety of electrical equipment.

Upon request, the PI Series can be supplied in different dimensions and mechanical configurations to meet the specific requirements of each application.

As ERIM's official distributor for the Iberian market, Rectificadores Guasch offers stock availability of a representative selection of the range, as well as full access to the manufacturer's catalogue, providing certified insulating solutions of European manufacture with full traceability for demanding industrial applications.
