Compression Seal Flanges

Compression seals are used when a watertight seal is required, but no fire rating is needed. Neoprene modules are inserted after the cables are installed for a water-tight seal and ease of pulling.

Fire rated MCT seals are used when a fire rated and watertight seal is required. Neoprene modules are inserted after the cables are installed for ease of pulling. They carry a 2 hour fire rating and come with all necessary hardware.

Neoprene modules for use with Roxtec frames. Provide Multidiameter™, the Roxtec technology based on removable layers, for perfect adaptation to a cable.

Termination Boxes

Transformer termination boxes, switchgear/MCC top hats, and other junction boxes designed and supplied by MP Husky guarantee the needed space to properly transpose the phases and terminate the conductors to the electrical equipment. Standard termination boxes are aluminum welded angle frame construction with bolted, removable side panels and welded fixed panels as needed. Outdoor boxes use gasketed removable panels, fully seam welded fixed panels, and an ESF type seal to ensure a weatherproof enclosure.

Environmental Seal Flanges

These fittings form a weatherproof seal with equipment/walls and can also be used for floor penetrations.
Conductors are sealed with RTV silicone sealant. Entrance fittings are furnished with all necessary hardware.
