Rubber Covers

INSULATOR COVERS

Insulator Covers, in orange, weather resistant Type II SALCOR®, are used with conventional line hose to cover pin-type insulators. All covers feature RIB-GRIP® construction to lock to the underside of the insulators. The large diameter arm overlaps the small arm of the adjoining cover on double arm constructions which provides complete insulation at the joint regardless of the varying distance between pins.

INSULATOR COVERS – EXTENDED LIP SU SYSTEM

• UH-ES Pin -Type Cover covers insulators up to ANSI standard C29.5 Class 5. The sides are cut to be used on small insulators without resting on the crossarm. When covering a 7” diameter insulator on a double arm construction, the ends of the cover will meet flush on 10.5” pin centers.
• The LRG-ES SU System Pin -Type Cover fits insulators 10.5” (267 mm) in diameter and is used with 2.5” (64 mm) Class 4 Extended Lip SU System Line Hose. Always use clamp pins to secure the device into position. Pinning rings have been placed on the cover arms to prevent separation.
• Post -Type Insulator Covers interlock with 1.5” (38 mm) Class 4 Extended Lip SU System or Conventional Line Hose. The PTHS-ES is for insulators up to 12” (305 mm) and the PTHL-ES is for insulators up to 16” (406 mm) in height. The PTHL-ES cover also has external ribs on the ears which secures 2.5” (64 mm) I.D. line hose. Always use clamp pins to secure the device into position.
• The Class 4 MRG-ES Universal Cover covers pin-type insulators through 8.5” (216 mm) diameter and 13.8 kV post-type insulators. A trim bead permits use on both 35 kV and 15 kV crossarm construction.
• The USC-ES Stirrup Cover is a lightweight cover that can be installed using rubber gloves or a hot stick. The USC also feature RIB-GRIP® construction and is meant to be used with Extended Lip SU Systems or Conventional Line Hose.

DEAD END PROTECTORS – CLASS 2 AND 3

Dead End Protectors cover 4.25” and 6” bells or polymer insulators with a skirt diameter of less than 6”. The protectors are made from orange Type II SALCOR® with RIB-GRIP® construction. OR101-ES has outer ribs that allow it to be used with 2” and 2.5” I.D. Conventional Line Hose when using the UC2-ES connector. The smaller OR114-ES may also be used to cover transformer bushings up to 4.75” in diameter. OR124-ES can cover polymer insulators up to 4.75” in diameter and 25” overall length including hardware.

Replacement Straps are available.

DEAD END PROTECTORS – CLASS 3 AND 4

Dead End Protectors quickly cover dead end bells or polymer insulators providing complete electrical protectionfor Class 3 and Class 4 applications. Easily installed and removed from an insulated platform or aerial device with rubber gloves or SU System Applicators, all styles have RIB-GRIP® construction to interlock with 1.5” (38 mm) I.D. line hose. The Class 3 U106-ES and U110-ES must be used with Connector End style line hose or separate Line Hose Connectors. OR134-ES, Class 4, accepts Straight Line Hose. The outer ribs interlock with 2” and 2.5” I.D. line hose when the UC2-ES SU System Connector is used.

CROSS ARM COVERS

To work on live lines safely, conductors encased in a line hose should never be placed directly on a cross arm. Cross Arm Covers reduce electrical stresses on line hose or jumpers. Cross Arm Covers fit standard cross arm pin spacing and each unit has interior ribs to minimize shifting on the arm.

CUTOUT COVERS

Flexible Cutout Covers can be used for overhead cutouts as well as for underground pad-mount applications.

All covers comply with ASTM D1049 specifications.
