Dear list

Regarding crosslinking of polyethylene.

Poly is crosslinkable, though as RM states, it is not easy. The
process uses dimucyl peroxide at high temperatures in a nitrogen
atmosphere to crosslink and cure. Cross linked polyethylene
(XLPE) is probably the best high voltage insulating polymer and
is used in supertension cable manufacture at up to 500Kv (that's
one big cable). If you can get hold of some supertension cable,
it makes a near perfect HV cap for Tesla coil use, though at
about 50pF per metre, your going to need a fair length and it
ain't cheap.
