PKV Quartz-Vaseline Paste 450g

Quartz-vaseline paste PKV (TU 36-513-G-69) tin can 0.45 kg.

Compound:
acid-free medical vaseline GOST 3582-52 and ground powdered quartz grade KP-2, or grade "B" in accordance with GOST 9077-59 (deposit "Mountain Khrustalnaya")

Packing:
tin can No. 3 450g (GOST 6128-81 - metal cans for chemical products).

Application:
- for mechanical connection and termination of aluminum wires and cables, for mechanical connection of busbars;
- to lubricate the inner surface of the connecting sleeves and cable lugs before crimping.
During crimping, ground quartz, which is part of the paste, destroys the oxide film and improves electrical contact, while vaseline protects the mechanical connection from corrosion.

The connection of wires by crimping is widely used in the installation of internal, external electrical wiring and overhead power lines. This method provides reliable contact, the necessary mechanical strength, and is simple to implement.
Crimping is performed with manual tongs, mechanical and hydraulic presses using replaceable dies and punches. To connect the cores, sleeves GAO, GA are used, for termination - tips TA, TAM, etc.

Crimping technology for aluminum conductors in connecting sleeves:
- select the type and size of the sleeves, as well as dies and punches in accordance with the dimensions of the sleeves;
- check the presence of factory lubrication in the sleeves and tips, in the absence of lubrication, the sleeves and tips are cleaned with a metal brush and - lubricated with PKV protective quartz-vaseline paste or zinc-vaseline paste;
- remove insulation from the ends of the cores: when terminating - at a length equal to the length of the tubular part of the tip, and when connecting - at a length equal to half the length of the sleeve;
- clean the ends of the current-carrying wires with sandpaper to a metallic sheen, wipe with a cloth soaked in gasoline, and cover with quartz-vaseline paste;
- put a tip or sleeve on the prepared cores;
- when terminating, the core is inserted into the tip until it stops, and when connected, so that the ends of the connected cores are in contact with each other in the middle of the sleeve;
- install the tubular part of the tip or the sleeve into the matrix and carry out crimping;
- insulate the connection with several layers of insulating tape.

Attention! It is not allowed to crimp a copper tip onto an aluminum core, since the connection will be fragile due to the large difference in the coefficient of linear thermal expansion of copper and aluminum. Crimping of single- and multi-wire copper conductors with a cross section of 4 mm2 or more is carried out in copper tubular lugs of type T or connecting copper sleeves of type GM. The technology of crimping copper wires is similar to the technology of crimping aluminum wires, except for applying quartz-vaseline or zinc-vaseline paste.
It is forbidden to carry out crimping with a hammer and chisel!
