IEEE 2780-2019 pdf free download.IEEE Standard for Insulation-Piercing Connectors.
cable temperature: the surface temperature of a cable conductor.
connection length: the distance between the outer edges ot thc blades both at the outermost ends.
insulation-piercing connector (IP(’): A self-scaling structural cable connector with piercing blades, shear bolts/nuts and an insulating shell. Piercing blades shall be able to pierce the cable insulating layer, and shear bolts/nuts with a controlled force shall, at an appropriate position, make a good electrical connection between piercing blades and cable conductor. The common usage is insulated cable connections including branch COnnect k. jumper coflflctiofl and ground connect ion
operating cable tensile breaking force: the tensile breaking torce of a cable installed with an insulation- piercing connector (IPC).

4. Technical requirements
4.1 General requirements
4.1.1 MaterIals and structure
IPC manufacturing shall be according to approved design drawings.
The ferrous metal of JPC components shall not he liable to rust and corrode.
Piercing blades shall have favorable electrical conductivity and shall have sufficient hardness to penetrate the cable insulation layer.
The insulating shell of the IPC shall have sufficient mechanical and electrical strength, strong anti-aging pcrtormance and excellent tiame retardancy. and shall be able to withstand operating temperatures without performance deterioration.
Connecting components of the IPC shall he equipped with a locking device to avoid losing connection during operation.
The IPC structure should be complete and he advantageous for installation.
The IPU shall he fastened with shear bolts/nuts, and deviation of the shear-torsion moment shall be within ±lO% ot’ the design value, The shear-torsion moment shall be determined by consensus of suppliers and users. lC shall withstand the electromechanical loads and environment requirements during installation, maintenance and operation.
4.1.2 Performance
Grip strength otlP(’ shall not be less than 10% of calculated tensile breaking ftrce of branch cable connected with this IPC. Operating cable tensile breaking force shall not be less than 95% of calculated tensile trcc of main cable connecting with this IPC.IEEE 2780-2019 pdf free download.
