Vaults (HUC-4)

Underground Distribution Switchgear Vaults

Hubbell Underground Distribution Switchgear Vaults utilize both Polymer Concrete and FRP con- struction to guarantee a simple, lightweight, and lower-cost alternative to the heavy, expensive concrete vaults used for underground distribution switchgear. Hubbell’s designs ensure freedom from rust and corrosion in all environments. Our unique technology enables us to construct vault enclosures with an unequaled blend of strength, durability, and ease of installation. We offer mul- tiple sizes for both four-way and six-way switchgear.

Designed To Be Superior

Lightweight - Hubbell Underground Distribution Switchgear FRP Vaults weigh just 4,000 pounds. Com- pare that to traditional concrete enclosures, which are incredibly heavy and can weigh as much as 20 times more. The greatly reduced weight means considerable savings on labor, time, and expense. Strength – Hubbell Vaults boast compressive, flexural, and tensile strengths three to five times higher than traditional concrete. Cost Savings - Unlike much heavier concrete models, Hubbell Vaults can be set with excavation equip- ment already on site.

Less Red Tape - No special transportation permits are required.

Fewer Headaches - No cranes are required for installation or access.

Cover Options - There are multiple easy-access cover openings available including torsion, polymer concrete, or ultra-lightweight composite covers. Torsion covers open to 180 degrees for ease of access. Additional Options - These may include composite work and switchgear platforms, composite ladders, racking, terminators, and pulling eyes.
