Fireproof Cable-NG-A (BTLY)
NG-A (BTLY) model flexible fireproof cable can be used in emergency after installation, and can also be used as 125℃ temperature-resistant halogen-free flame-retardant cable and fire-resistant cable in normal times. This series of cables has a wide coverage, which not only overcomes the defects of rigid fireproof cables, but also gives full play to the advantages of flexible fireproof cables. It also provides practical products for key projects, so that modern projects can achieve the effect of short circuit without burning and burning without short circuit in electrical lines. It can not only be successfully applied in fire protection performance such as fire alarm and emergency life-saving circuits, but also can be promoted and applied in high-density current and other special performance requirements.

Structural features
The structure of NG-A (BTLY) mineral insulated fireproof cable includes the following parts:
Conductor: It adopts high temperature resistant, non-combustible inorganic mineral insulation material (such as mica tape/ceramic silicone rubber tape), which can be the first or second type of copper conductor1.
Fireproof insulation layer: It adopts high temperature resistant, non-combustible inorganic mineral insulation material to ensure that the cable will not burn in a fire.
Metal sheath: The aluminum sheath is continuously extruded with good bending properties.
Isolation layer: Polyethylene isolation layer, with waterproof and color separation functions.
Fireproof mud: Inorganic mineral material is extruded around the cable gap and the cable, which has the same fireproof performance as magnesium oxide.
Low smoke halogen-free outer sheath: It adopts low smoke halogen-free plastic material with good flame retardant and protective effects.
