TOPIC: Dummy core for cable

Dummy core for cable 2 years, 3 months ago #361

We have been manufacturing low smoke fume cables. We are using dummy cores in cable which have 5 or more cores (insulated conductors?). I want to learn which polyethylene can be used to these produce dummy cores. I have learned that is low density polyethylene. Any advice?

Re: Dummy core for cable 2 years, 3 months ago #362

Hi there serdar1970,

Could you please give us some more information regarding the dummy cores?

A) Are the dummy cores say just to give a round core over which to extrude the jacket? OR....

Are these dummy cores also to provide a passable low smoke cable core.

If the answer is "B" I would tend towards a highly filled polyolefin like EVA.
