1. Analysis
HSH-type cable fire-resistant seal filler is mainly used for a variety of ships on the cable throughout the device in the filling filler, can also be used in construction and power supply system at the perforated seal packing.
DL200 expansion block material for the HSH-type filler before filling as an indispensable sealing material, and the other can be used for other complex hole sealing materials.
HSH-type packing, DL200-type block material and DL200 series fire blocking material non-toxic, non-corrosive, harmless to human body.
2. Technical performance
Fire resistance: to the International Convention on the Safety of Life at Sea (SOLAS) A-60 (grade) (ceramic for fire), A-0 level (steel for fire) fire performance.
Watertightness: according to the International Electrotechnical Commission (IEC) standards 92-3 (1965) and CB3386.1-2-93 and the appendix to the standard pressure 0.1Mpa one hour does not leak. With these two products perfusion cable box (tube) watertight performance up to 0.25Mpa one hour does not leak, more than international and domestic standards. Resistance to vibration, shock, high temperature, low temperature, heat and various properties. After the above test, the cable box (tube) under 0.1MPa pressure does not leak for one hour.
