Appeal No. 1996-3350
Application 08/187,114
increases said inner diameter of said tubular elastic sleeve
by at least 120% with respect to its diameter in its
unstretched condition, said support having a rigidity
sufficient to maintain said tubular elastic sleeve in its
elastically expanded condition and being removeable from
within said tubular elastic sleeve;
said tubular elastic sleeve having a modulus of
elasticity in the range from 5 to 0.05 MPa and upon removal of
said tubular support from within said tubular elastic sleeve,
the internal bore thereof returns substantially
instantaneously to a diameter at least 10% less than said
first smaller outer diameter of said insulation by reason of
elasticity of the sleeve and without heating;
the radial thickness of said sleeve and said electrically
insulating layer being selected to cause a radially inward
pressure on a cable electrical insulation of said first,
smaller outer diameter, after application thereto and
substantially instantaneously after removal of said tubular
support, of at least 0.1 MPa; and
said electrically insulating layer of said tubular
elastic sleeve being made of a cross-linked polymeric material
selected to have an instantaneous residual deformation of at
least 23% upon removal of said tubular support at room
temperature after the insulating layer has been subjected to
an elastic expansion of at least 170% for a storage time
equivalent to at least 24 months at room temperature.
