2020-11-25

BBS blocking, by the AB two-component site mixing and blending can be quickly self-levelling, followed by expansion curing forming a closed body. Suitable for: high and low voltage switchgear, box-type substation, cable branch box, open and close, ring network cabinet and other power equipment cable room in and out of anti-condensation blocking, completely blocking the source of condensation moisture. With moisture, fire, corrosion, flame retardant, environmental protection, aging resistance, etc., to eradicate condensation and small animals into the cabinet to produce electrical safety hazards.

　　BBS blocking，After mixing and blending by AB two components on site, it can be quickly self-levelling, and then expand and solidify to form a closed body. Suitable for: high and low voltage switchgear, box-type substation, cable branch box, open and close, ring network cabinet and other power equipment cable room in and out of anti-condensation blocking, completely blocking the source of condensation moisture. With moisture, fire, corrosion, flame retardant, environmental protection, aging resistance, etc., to eradicate condensation and small animals into the cabinet to produce electrical safety hazards.

　　Imitations andBBS blockingComparison of the group material genuine, the appearance of the gap is huge, the internal performance is a world of difference, after expert experimental analysis, imitations in the density, bubble holes, substrates, etc. are not up to the standards of anti-condensation governance, and one of the most fatal hazards is the production of a coking layer.

　　BBS blockingThe flow rise technology used in the group material has very high requirements for research and development, production and other aspects. The core technology of some imitations and cottage products on the market is not up to standard, and they are unable to control the speed of temperature climb during the chemical reaction, and the reaction is not completed to produce a coking layer.

　　Coking layer formation process generates a temperature of 150 ℃ ~ 200 ℃, far more than the bottom line of the safe operation of the cable, resulting in high-temperature erosion of the cable, cable sheath aging cracking, loss of the design of the insulating properties of the cable, easy to cause the cable ground breakdown, at the same time, coking layer of material is hard and brittle, very difficult to remove the integrity of the need to use a violent tool such as an electric hammer, often accompanied by the removal of the coking layer, the outer wall of the electrical box, cable often accompanied by the removal of the coking layer, the outer wall of the electrical box, the cable jacket, the outer skin of the cable will also be completely destroyed, resulting in irreparable damage.

　　The use of imitation base plate blocking lost airtight, so that condensation can take advantage of the cable and the cable is damaged by high temperature. These are like time bombs, threatening the smooth and safe use of electricity in the area all the time.
