Caution: All work must be performed in a well ventilated area.
PREPARATION OF THE IMPREGNATED ROPE END:
- Insert the rope through the base of the fitting until it extends a sufficient distance from the fitting mouth to permit end preparation.
- Measure and mark off the length of the jacket to be removed. This length is primarily dependent upon the depth of the fitting basket; however, allowances also must be made to insure that the rope end will not protrude above the potting medium in the finished termination.
- Wrap vinyl tape over the jacket end where it will extend into the fitting to increase the rope diameter and provide a snug fit.
Note: If jacket had deep interstices, put putty on jacket before wrapping with vinyl tape.
- Remove the jacket using a soldering gun equipped with a cutting tip. Be sure the heat generated by the gun does not exceed 500°F (260°C). Figure 1
- Put putty in the interstices around the central core member to prevent leakage of resin into rope.
- Unlay the bare end of the rope down to the individual impregnated yarns, forming a broom. Figure 2 shows a finished end ready to be potted.
- Pull the broomed rope end down into the fitting, positioning it so that the jacket extends the proper distance into the basket and the upper end of the broom will be completely embedded in the potting medium. Make sure the fibers are evenly distributed within the basket.
- Seal the area where the rope enters the fitting with putty or duct seal to prevent leakage of the resin from the basket.
- Secure the fitting in a vertical position being sure that the axes of the fitting and rope are in line and that the sealant at the base of the fitting remains in tight contact with the fitting and rope . Figure 3
MIXING POURING AND CURING
Note: Use SOCKETFAST BLUE potting compound. Once mixed, the compound has a gel time or pot life of 20-30 minutes at 70°F (21°C). Gel time increases at lower temperatures and decreases at higher temperatures. The compound is designed for optimum application performance at 75°F (23.9°C), and should not be used at material temperatures below 65°F (18.3°C) or above 85°F (29.4°C). When the ambient temperature is out of this acceptable range it will be necessary to warm or cool both the fitting and the resin components, prior to mixing and pouring.
- Mix the potting compound following the manufacturer's directions.
- Pour the compound into the fitting at a rate which allows displaced air to escape and which does not flood the top of the basket. Figure 4
- After the compound has gelled, wait 30 minutes or until the heat has dissipated before moving the assembly.
- A cure period of 24 hours at 65°F (18.3°C) or higher is required to attain satisfactory holding power. Curing at lower ambient temperatures can be accomplished by placing and maintaining the finished termination in a temperature environment of 65°F (18.3°C) or higher.
