2.Product features

Flexible mineral insulated fireproof cable can maintain normal operation for a while after the fire broke out. It ensures line security and is beneficial for
 rescue operation. The cable has passed C、W、Z grade tests required in BS6387 and BS8491 Standard. The tests are 950℃, 180min combustion test, 650℃ water spray test and 950℃ mechanical impact test.


3.Product structure design

Excellent fire performance--It conforms to BS6387 and BS8491 Standard.

Environmental friendly materials--It’s halogen free, low smoke during combustion.

Flexible structure--There’s no any other similar metal sheath except for
 stranded copper wire. Environmental friendly isolation
 material is much softer than others. The complete cable
 is more flexible and of good fireproof performance.

Easy installation-- The cable can be delivered in coils according to the customer's demand on length. There is no need to use connectors and appropriative terminals. It can be installed in accordance with installation methods for ordinary cables.

Prefabricated branch cable system—We can prefabricate branch joints to meet
 the user's need. The system makes
 installation more convenient.
