TZM
APPLICATION
Heat shrinkable sleeves with a closing strip are suitable for repair sheath of communication or power cables (or another products).
MARKING
Marking consists of character sign TZM and a numbers to indicate the dimension of sleeve (as shown in Tab. 2).
CHARACTERISTICS
The sleeve is made from cross-linked polyethylene (properties of material are shown in Tab.1), it has an oblong form with two rails for closing strip. The inner surface (which arises by closing of sleeve) is provided with a layer of hot melt adhesive, which after installation guarantee tight and reliable bonding to the cable sheath (or other basic material). The closing strip is delivered together with a sleeve. It is made from stainless steel and has a profile in form of character "C" with blank spaces to ensure the necessary forming.
Heat shrinkable sleeves with a closing strip TZM are produced and delivered according to PN VUKI 22 004.
