Electrical conduit means building electrical installation work for the protection and security of wire or cable conduit pvc line pipe, which allows the penetration and replacement of the wire or cable. "Source resistance through" PVC-U rigid retardant electrical insulation pipes and fittings is the main raw material polyvinyl chloride resin, add various stabilizers, anti-aging agents, impact agents and other additives extrusion and injection molding processing threading pipe and fittings. Mainly used for electrical, communications cable casing. "Source resistance through" the introduction of advanced production technology and equipment pvc line pipe manufacturers, high-quality PVC, processing aids and environmental quality nanomaterials for raw materials, scientific compounding to produce high-quality PVC-U retardant rigid electrical conduit. "Source resistance through" in order to ensure product quality, production of the whole process of strict implementation of the relevant process requirements, depending on the raw material, to develop reasonable and effective process. The company is now producing light, medium and heavy three models, D16 ~ D50 total of eight specifications of the electrical conduit, respectively, for different pressures of the occasion. Wherein the light pipe is suitable for surface, while the medium and heavy pipe can withstand pressure of more than 750N and 1250N respectively, it can also be surface mounted dark spreads in a variety of concrete and not due to pressure and rupture. Taking into account the special nature of the product purpose, increasing the flame Henan pvc line pipe in the formulation, thus ensuring that the product is safe and reliable in use. Henan source resistance Technologies Ltd. currently has two high-quality domestic brands retardant PVC electrical conduit pipe automatic production lines, Qilu Petrochemical SG5 resin: PVC as the main raw material, impact modifiers, lubricants, stabilizers , flame retardants and other additives as auxiliary materials, can produce Ф16 ~ 75mm light, medium and heavy three models pvc line pipe 20mm, annual production of 3000 tons of pipe. Application areas: electricity, telecommunications line jacket, construction embedded, wall, underground cables and the like. pvc wire tube 40, City of pvc line pipe, source resistance provided by the Henan source through resistance Technologies Limited. Henan source resistance Technologies Limited (www.yuannaitong.com/lxynt.html) strong, credible, in Zhengzhou, Henan's industry-specific equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead source resistance into the brilliant pass and you work for a better future!
