Chai Jin Tianjin Cable Bridge Co. [1], supporting the project as a cable tray fire bridge cabling project how to sell, there is no specific regulatory guidance, a manufacturer specifications program lacks versatility, therefore, the design selection process each system should be based on the weak cable seem the type, quantity and reasonable application of the selected bridge. (1) determine the direction: According to the building floor plan, combined with air-conditioning lines and electrical lines and other settings, easy maintenance, and the cable routing density to determine the best route cable trays. In the interior, as far as possible along the wall of the building, columns, beams and slabs erection, take advantage of such a comprehensive pipe gallery set up fire bridge, should be in the side or top of the parallel pipeline erection, and consider deflectors and branch lines to avoid cross like no other pipe racks to borrow, you need inception (branch) column. 2, such as fire when combined with the power cable tray tray how much money should be power cables and electronic cables between each straight side of the middle separated by diaphragms. 3, weak cable in combination with other low-voltage cable bridge, should be strictly enforced select an outer shield weak system of weak cable, to avoid mutual interference. Chai Jin Tianjin Cable Bridge Co., Ltd. [] control resin impregnated plastic cable tray slot, the impact of small articles in the past, the production is not large, but for FRP cable tray large cross-sectional area, the use of yarn increased sharply, required Dipped huge tank size, storage is the amount of resin up to 200kg, and mold large, large heat storage, heat slowly, causing large die glue reflux, high temperature, continuous production could easily lead to resin plastic tank resin; and even short-term deposit the emergence of cable tray or trough topical gel polymerization phenomenon of violence. For this reason, plastic tank and die by water cooling system. Pultrusion large due to the large cross-sectional area cable tray products, but has a thin thickness, pulling out of the product from the mold does not reach a certain degree of cure, do not have a high strength fire bridge price, easy to deform. In addition to the method of forming zone extended on the device, but also added styling guide rollers, controlled deformation of the product, to ensure FRP cable tray size setting after fully meet the design requirements and use requirements. Which is better _ Chai Jin fire bridge cable bridge (certified) _ Qinhuangdao fire bridge provided by the Tianjin Chai Jin cable bridge Limited. Chai Jin Tianjin Cable Bridge Co., Ltd. (www.tjcjdlqj.com) is Tianjin, metal building materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chai Jin leader in cable tray with the staff warmly welcome all inquiries negotiations to create Chai Jin cable tray a better future.
