ACCESSORIES FOR STRAIN CARRIERS
- FLV10460-1
It is highly recommended to provide the installation of the safety nut as soon as the trunnions are installed to the strain jacks. This ensures additional safety during the straining operation as a support to the trunnions.
- RE401-2066 / RE401-2068
The small and large trunnions have been specially designed for the attachment of the yokes to the strain poles. They are made of cooper alloy and provided with ball-thrust bearings to make them easier to operate during the rotation on the strain jacks, using the ratchet wrench (RM1948-3).
- RE401-0138
Adjustable pole clamps are made of heat-treatment aluminum alloy and have been designed to engage the hot end yoke to the strain poles. The adjustable pole clamps can be easily moved over and positioned between the steel pins located down the pole, either manually or using a hot stick.
- RE401-1998 / RV401-0157 / RV401-0158
The Tongue type Strain Jacks are used for attachment to the strain poles as an adjustment tool when straining insulator strings.
The Tongue type Strain Jack is attached to the eye of the strain poles through the existing head on one of its ends.
- FLV17755-1
Trunnion Gauges, also known as “Go/No Go” (or Pass/Fail), are made of steel and are essential for periodical check of the trunnion threads to ensure that there is no thread wearing. This gauge is provided with 0.5 mm (0.02") wider threads. Thus, if the
trunnion allows the introduction of the gauge, even only partially, the thread wearing of the trunnion is greater than 0.5 mm (0.02") and, therefore, improper for use.
- RH4785-1 / RH4785-2 / RH4785-3 / RT400-0025
The Clevis Type Strain Jacks are used for attachment to the clevis-eye strain poles (RH1949-113 / RC400-0612 and RC400-0613), as an adjustment tool when straining insulator strings. The Clevis type Strain Jack is attached to the eye of the strain poles,
through the existing head on one of its ends.
- RM1948-3
The Reversible Ratchet Wrench was specially developed for use on hexnuts and trunnions on single and double strain carriers.
- FLV16054-1
The Reversible Ratchet Wrench was developed for use on hex-nuts and trunnions where more effort is required.
