The advantages of LSZH jacket material

LSZH (Low smoke zero halogen) is a low smoke zero halogen material

To evaluate the combustion performance of finished wires and cables, flame propagation tests must be conducted according to IEC 60332-1, -2, -3 standards. Simultaneously conduct smoke density measurements: ASTM E 662 (cable materials) and IEC 1034-1, or -2 (cables).

One of the superior comprehensive performance: about environmental cracking phenomenon

Some products both domestically and internationally have experienced cracking during use, seriously affecting the service life of cables. The phenomenon of environmental cracking is a complex problem influenced by multiple factors. It is generally believed that the causes are closely related to residual stress in the LSZH sheath layer after product processing, debonding at the interface, and resin hardening and brittleness.

The elongation at break provided by Jiangsu Elesun cable is greater than 200% and its exceptional aging performance provides beneficial conditions to overcome this phenomenon.

The second superior comprehensive performance: outstanding thermal deformation properties. Maintaining the minimum thermal deformation properties when heated undoubtedly has its practical value. Under hot pressure conditions, experiments have shown that it can reach the standard of 90 ° C or 100 ° C.

In addition, the thermal deformation properties are more prominent under non compression conditions. For example, at 120 ° C, under free hanging conditions, it remains unchanged for 240 hours, while many similar products become muddy and fall off after only 3-4 hours of heating.

Superior comprehensive performance three:

High flame retardant and low smoke emission,comprehensive performance, which can meet the IEC 1034 standard
