ПМЛО |
braided tinned copper wires, light |
Braided wires of ПМЛ, ПМЛО models for У2 climatic modification are made of copper wire tinned with tin-lead solder not lower than ПОС-40 and for Т2 climatic modification -copper wire tinned with tin solder.
Braided wires of ПМ, ПМОmodels are made of copper wire. Braided wiresshall not have oxidized surfaces. Light blueing is acceptable.
