SMC cable boxes than stainless steel junction box can adapt to coastal areas


Scope of application

GPQ-A series cable transfer box is used for interface equipment cable access network backbone optical cable and branch cable joints, with fiber splicing, storage and distribution function, the ground or aerial installation.

Characteristic

The box body uses the high strength (glass fiber reinforced unsaturated polyester plastic SMC) after high temperature molding, long service life, anti-aging, anti radiation; surface without any protection, with all-weatherprotective function

The box body is thick, has good heat insulation effect, can effectively prevent the condensation of water vapor

The door is made of special sealing door sealing, waterproof and three point type door lock pin lock, safe and reliable, good sealing performance

 uses 12 core welding wire integration module

 suitable for FC, SC optical fiber adapters installed

We have reliable optical cable fixing and grounding protection device

 applicable standards: YD/T 988-2007

8.4, material

The SMC Sheet molding compound abbreviation, namely the sheet molding compound. The main raw materials by SMC special yarn, unsaturated resin, low shrinkage additives, fillers and various additives. It was in twentieth Century at the beginning of the sixty's first appeared in Europe, around 1965, the United States, have developed this technology. Our country in the late 80's, the introduction of foreign advanced SMC production line and production technology. SMC has superior electrical performance, corrosion resistance, the advantages of light weight and engineering design easy, flexible, its mechanical properties can be comparable with the part of the metalmaterial, which is widely used in transportation, construction, electronics and electrical industry.

The GTGXF communication cable transfer box material and view -- the box using SMC unsaturated polyester glass fiber materials by high temperature molding process, the surface smooth, uniform color, not easy to scratch. Has the characteristics of high strength, corrosion resistance, aging resistance. Can resist changes in climate andenvironment.

 double welded distributing disc, make full use of the upper and lower surfaces of the plate, set welding and wiringin one, can be used to install FC, SC adapter card. Each disc can be installed 12 adapters, adapters, tilt angle of 30 degrees in the splice tray, can ensure the curvature radius of optical fiber.

● suitable for common cable and broadband cable wiring, space, all optical cable, optical fiber wiring in any position can effectively protect.

Door lock the box has the function of preventing the destruction of good, opening and closing is flexible and reliable,the box door opening angle of 120 ° ', good sealing performance outer box using SMC unsaturated polyester glass fiber. The plate thickness 1.5mm, the inner layer uses a 1.5mm high quality cold rolling steel plate, are from theShanghai Baosteel procurement.

Process

The box is made of SMC unsaturated polyester glass fiber materials by high temperature molding process,enhancing module plastic solidification under high temperature and high pressure molding. SMC series mold plastic molding process molding:: temperature 150 ± 5 ℃ holding time: 60-70s / mm molding pressure: 10-20Mpa specific process depending on the product and mold structure and decide, if the thickness is thicker, the temperature should be slightly low, general molding temperature is 135 ℃ -145 ℃, more complex shapes, forming pressure the higher the.

The high mechanical strength, good flame retardant -- the case due to the adoption of SMC composite materials,light weight, high mechanical strength, and has good flame retardancy. The door is made of the longitudinal length of the hinge, not easy to deformation, mounting interchangeability good.

The corrosion resistance, aging resistance, electrical insulation and strong -- the case of corrosion resistance, aging resistance, good protective property, high electrical insulation and strong, able to adapt to strong acid, alkali and other harsh environment.

The high temperature resistant, anti condensation -- the case due to the adoption of SMC composite materials,which can not be compared with metal material heat insulation performance, high temperature resistant, and effectively prevent the condensation of water vapor.
