The closed card is designed for 10-1000KV potential or power failure to replace the porcelain bottle. It is mainly used for any piece of porcelain bottle in the tension-resistant porcelain bottle string or straight-line porcelain bottom string. Tighten the broken porcelain bottle string on both sides, loosen the middle one and replace it at the same time, and then release the two tightened porcelain bottles. Either the job can be done or the end clamps can be produced.
Applicable: porcelain bottle insulator; glass insulator
Tools should be used when using: canceller (sold separately)
Front and rear hanging points: steel cap.
