| Detailed Product Description： |
The explosion-proof heating cable (price - manufacturers - offer) the first branch of the Tianjin Cable Plant - (referred to as "cable One Factory") was established in 1971, is located in Langfang City, Hebei Province. Is a professional production and sales of production, sales professional is one of the wire and cable manufacturers. ?????? The main products are: flame retardant communication cables, railway signaling cable, coal mines, the coal mine used flame retardant control cable, coal flame retardant signal cable, power cable, control cable, computer cable, signal cable, communication cable, and a variety of flame-retardant, high temperature, fire-resistant cables. The company currently owns 500 employees, the company has consistently adhered to "quality first, customer first, quality service, abide by the contract's purpose, by virtue of high quality products, good reputation, quality service, products sold throughout the nearly three dozen provinces, municipalities and autonomous regions and exported to Europe and other countries. Wholeheartedly with the domestic and foreign businesses win-win cooperation and common development, create brilliant! ?? The products are widely used in the field of energy, chemicals, shipbuilding, coal, building materials, metallurgy, transportation, electronics, scientific research, communications and defense, the product has supporting joint chemical plant in Tianjin, the Jiuquan Satellite Launch Base, Beijing Netcom, and telecommunications engineering Bureau, Shandong Yanzhou Mining Group, Shanxi Datong Yangquan mine, and other key projects at home and abroad and projects received by customers. Plastic power cables using high quality rubber and plastic sheathed cable jacket to protect the plastic power cable core, also has a good leak-proof electric effect, I plant the production of plastic power cables are homogeneous high-quality material processing, the current can supply plastic to force cable companies or retailers sourcing from factory! [ Contact: Bijin Cheng Tel: 0316-5960412 Mobile phone: 13131682147] I plant more users directly to the cable of my plant purchase of various model specifications, we will be quality products, low prices to meet you soon!

Outline

|
Industrial proof thermocouple, thermal resistance as the temperature measurement and control sensors and display instrument to directly measure and control the temperature of the gas, liquid and steam in the production process.
I plant the production of chemical proof thermocouple, thermal resistance proof performance issued by the State "explosive environment with explosion-proof electrical equipment" standard design and manufacture of thermoelectric properties according to IEC standards, and explosion-proof by the National Instrument Safety Supervision Station tested.
Proof thermocouple, thermal resistance of the structure, principles and assembly methods are basically the same, the main difference is explosion-proof products junction box (housing) in the design of high strength aluminum alloy die casting, and has enough internal space, the wall thickness and mechanical strength, thermal stability of the rubber seals are in line with national standards for explosion proof. So when the explosive gas mixture within the junction box when the explosion occurred, the pressure will not damage the junction box, and the resulting heat can not spread out - explosive. Strict compliance with the product rule, the product can achieve reliable explosion-proof effect.

Working principle
|
|
|
Explosion proof thermocouple the gap flameproof principles, the design of the junction box and other components of adequate strength, and all will produce a spark, arc and dangerous temperature components are sealed in the junction box cavity, the cavity when the explosion occurred, through the flame and cooling of the joints clearance, after the explosion of flame and temperature transfer less than a cavity, which carried out the explosion-proof.
