(Specification)Standard Specification for Clampstick Type Live Line Tools
Standard Specification for Clampstick Type Live Line Tools
ABSTRACT
This specification applies to the clampstick type live line tools to ensure manufacturing processes and materials are compatible and no deterioration of components occur during the assembly process. Neither the FRP tube and rod, foam filling, or the bonding adhesive shall deteriorate during the prescribed mechanical and electrical test. The external surface of the FRP shall be uniform, symmetrical, and free of abrasions, scratches, blemishes, and surface defects. The mechanical design test and electrical design test procedures are presented in details.
SCOPE
1.1 This specification applies to the Clampstick type live line tools to ensure manufacturing processes and materials are compatible and no deterioration of components occur during the assembly process.
1.2 This specification establishes the technical characteristics for clampsticks.
1.3 This specification applies to clampsticks both hollow and foam-filled.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
The following safety hazards caveat pertains only to the test portions of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicable of regulatory limitations prior to use.
1.5 The use, maintenance, and in-service testing of this equipment is beyond the scope of this specification.
