Standard fire resistant cables for use primarily in fire detection, fire alarm, voice alarm, and emergency lighting circuits. These cables are designed to continue to operate for a period of time in a fire situation. ‘Standard’ fire resistance is recommended for general use.
Compressed Conductor easy for installation, UV - resistant , Low Smoke,halogen Free in fire condition , Fire_Proof
Heat resistance:
XLPE with a three-dimensional network structure has excellent heat resistance. It will not decompose and carbonize below 200℃, the long-term working temperature can reach 90℃, and the thermal life can reach 40 years;
Insulation performance:
XLPE maintains the original good insulation properties of PE, and the insulation resistance is further increased. The dielectric loss tangent value is very small, and it is not greatly affected by temperature.
Mechanical properties:
Due to the establishment of new chemical bonds between macromolecules, the hardness, stiffness, wear resistance and impact resistance of XLPE have been improved, thereby making up for the shortcomings of PE being vulnerable to environmental stress and cracking.
Chemical resistance:
XLPE has strong acid and alkali resistance and oil resistance. Its combustion products are mainly water and carbon dioxide, which are less harmful to the environment and meet the requirements of modern fire safety.
