Building The Energy Web

HiReli LLC. was founded in 2001 as the G&W Electric representative for northern New Jersey. Since then, HiReli has grown to a group of 17 talented individuals covering all or parts of eight states from New York to Virginia. HiReli now also represents Hanhe Cable Systems and Magnetron Transformers. The HiReli Supply Division offers many other products, and HiReli is a WBE, which can assist with contracts requiring MWBE participation.

G&W is still the biggest product line, sales have grown by a factor of 100 since founding and today. The HiReli G&W territory now covers New York City and surrounding counties, Long Island, New Jersey, and Eastern Pennsylvania. G&W has undergone massive expansion of products and facilities over this period, and HiReli is proud of the contributions to this effort. G&W is a leading global supplier of SF6 and Trident Solid Dielectric insulated switchgear, both pad-mounted and submersible, overhead Viper Reclosers with SEL control, and HV and LV Cable Accessories from 5kv to 345 kv, system protection CliPs, plus LaZer Distribution Automation.

Magnetron Transformers are well known globally, not only for distribution and power transformers, but for unique variable speed drive multi pole transformers and integrated drive power supplies.

The Magnetron S.A.S. factory in Preriro, Columbia is very impressive. What is now Magnetron started life as a Westinghouse transformer plant, any old timers out there will recognize the Westinghouse heritage. The new Magnetron plant has a specialized fully instrumented test lab that can provide live “witness testing” from a remote location via the internet.

In addition, Magnetron transformers qualify as “Buy American” products under a joint US – Columbian treaty.
