Díky redline se okamžitě dozvíte o:
Ušetřete si čas i starosti!
Díky Redline již nebudete muset ztrácet čas zjišťováním, co se v nové normě změnilo. Redline Vám ušetří čas a zaručí, že se o změnách v normě dozvíte.
Cena
Pokud si zvolíte možnost "Platná norma + Redline", pak dostanete oba dokumenty! A co je nejlepší, cena Platné normy + Redline je pouze o něco málo vyšší než cena samostatné platné normy.

This specification covers thermoplastic polymer insulation consisting substantially of polyethylene considered suitable for use on electrical wire or cable with specified maximum conductor sizes that will be used for continuous operation at specified conductor temperatures and maximum voltage ratings for power application or series lighting. Since the insulation material cannot be tested unless it has been formed around a conductor, tests shall then be done on insulated wire or cable in this specification are solely to determine the relevant property of the insulation material and not to test the insulated conductor or completed cable. Materials shall conform to physical properties as to unaged tensile strength and elongation at rupture, tensile strength and elongation at rupture after air oven aging, absorption coefficient, and insulation thickness. Insulations shall also be tested for their electrical performance in terms of AC and DC voltage, partial discharge, and insulation resistance.
