Charge-actuated and hydraulic cable piercing

CABLE SPIKING TOOL ACTUATION

Charge-actuated vs. Hydraulic-actuated:
The following comparison of the benefits and features of the two primary actuation methods for cable spiking or piercing tools is provided as a service to users or potential users of these lineworker safety devices. Whether charge or hydraulic actuation is utilized, both will achieve a safe work environment for cable maintenance personnel.

Safety Benefits and Tool Features	Charge-actuated (power loads)	Hydraulic-actuated
Remote Operation	Yes	Yes
Personnel isolated from cable during spiking	Yes	Yes - providing non-conducting hoses are used
Result from spiking a live cable	Minimal tool damage and cable vaporization	Increased vaporization and escaping gases due to presence of hydraulic fluid
Maintenance	Low - Clean with light machine oil after each operation	Higher than charge-actuated - Leaks in hydraulic hoses and typically, if the tool is inactive for a period of time hydraulic seals tend to dry out
Additional Equipment	Power loads are readily available locally. All parts can be ordered through Spike Tool Distributors.	Non-conducting hydraulic hoses, battery pack or field generator, and an intensifier for 10,000 psi
Operator Training	As with all safety tools and equipment, SPIKE Tool Inc. recommends operator training at the lineworker apprenticeship level. May be required as per regional or national health and safety regulations. Internal training program acceptable.	Internal training required.
Cost		3 to 4 times the cost of the SPIKE Tool
