An insulating sleeve with a rated voltage of 500V is sleeved on the pliers handle. As a common pincer tool which can be operated in a narrow working space. ,it is mainly used to cut single and multi-strand wires with thinner wire diameters, as well as to bend single-lead wire joints, peel plastic insulation, etc..  it is an electrician long nose pliers (especially one of the tools commonly used in assembly and repair work such as interior equipment) 

Long nose pliers is one of the typical tools using the principle of leverage.

The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)

Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.

Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ（methane 6.5±0.5%）。

Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.

The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
