Igeelee is an enterprise specializing in manufacturing, marketing, and R&D of electric tools, hydraulic tools, powered tools, and so on. Our pipe tools are widely used in the pipeline industry for plumbing and heating installation.

Power tools are divided into three categories according to the way of electrical protection: a. Class I tool; b. Class II tool; c. Class III tools.

Class I tools are common types of power tools with rated voltages exceeding 50 volts. Class I tools rely on basic insulation for protection against electric shock and include an additional safety measure. The specific method is to connect the accessible electrically conductive parts with the protective (grounding) wires that have been installed in the fixed-line so that the accessible electrically conductive parts do not become charged in the event of basic insulation damage. The plug of the Type I tool is a three-prong plug.

Class II tools are power tools in which the insulation structure is all double insulated. The specified voltage exceeds 50V. Class II tools do not allow grounding devices. Generally, it is an insulated casing. In general, the design and manufacture of Class II tools place the operator’s personal protective equipment on the tool in a reliable and efficient way, so that the tool has double protection current to ensure that when the basic insulation damage fails in the event of failure, Electric shock protection is provided by adding insulation and reinforced insulation. Class II tools must be reinforced with a reinforced power plug, and the power plug is not detachable with a flexible cable or cord. Class II tools only allow non-reconnectable two-pin power plugs. Class II tools are marked with “back”.

Class III tools are safety voltage tools. Its rated voltage does not exceed 50V, and the protection against electric shock relies on the supply of voltage from a safe voltage and does not generate a voltage higher than the safe voltage inside the tool. Class II tools should be used in general processing locations.

Class III tools are safety voltage tools. Its rated voltage does not exceed 50V, and the protection against electric shock relies on the supply of voltage from a safe voltage and does not generate a voltage higher than the safe voltage inside the tool. Class II tools should be used in general processing locations.
