Rigid & Flexible Mining Cable
In addition to the classification of specific models, mining and tunneling cables can be categorized into rigid and flexible cables.
The internationally recognized magnesium oxide mineral insulated cables (often IEC 60702-1:2002) have a solid conductor made of copper, unlike the stranded or flexible conductors used in ordinary cables.
BTT Rigid Mining Cable
BTT series is the only internationally recognized mineral insulated cable, which is made of a seamless copper pipe sheath, filled with magnesium oxide crystal powder as insulating material, and the conductor consists of a single strand of copper rod.
Internationally recognized mainly depends on its use of real high temperature materials, including copper conductor and copper sheath melting point is 1083 ℃, and magnesium oxide mineral insulation layer melting point is up to 2800 ℃, so that the line in more than 1,000 ℃ high temperature can still be operated safely.
BBTRZ Flexible Mineral Cable
BTT Rigid Cable (T) is changed to (B), with B standing for mineral. The product structure consists of copper stranded wire, gold mica tape insulation, irradiated cross-linked polyethylene water barrier, magnesium hydroxide mineral fireproof sheath, and low-smoke halogen-free sheath.
The BBTRZ series produced by VERI cables is very cost-effective has been highly recognized by many project partners and users, and has been used in a variety of large-scale building fire lines.
In addition to the above, there are also flexible mineral cables named BTTRZ, YTTW, and RTTZ. But in fact, these three named MI flexible cables have the same structure form, which is called Flexible Rolled Copper Sheathed Mica Tape Mineral Insulated Cable. It consists of multi-stranded copper stranded wire, mica tape mineral insulated winding, non-alkali glass fiber dense filling, copper tape longitudinal package welded copper pipe sheath.
Advantages of VERI Cables
Our cables are built to withstand the harshest environments, including exposure to mechanical stress from underground, grease, vibration, acidic corrosion, and even deep water submersion. In addition, the mining cables we supply can work safely in confined spaces, with some wires offering protection to personnel and high-value equipment in the event of a fire by reducing smoke and fumes due to their LSZH construction qualities.
As an advanced supplier of cables and accessories for the mining tunnel boring industry, we provide a range of technical solutions, from cable production specifications and design to quality acceptance and shipment to ensure the shortest possible delivery times.
Mining Tunnel Infrastructure & Equipment Cables
VERI Cables’ technical engineering team has extensive experience in some of the largest underground mining and tunnel boring projects. Our goal with every cable is to achieve high performance in challenging environments and minimize risk. Every customer and partner who has worked with VERI has commented on the high quality of the products and the level of service we provide, and we are the partner of choice for many projects in the mining industry.
The most critical step in underground mining operations is tunneling, and VERI offers a full line of underground railroad signal cables, and underground armored fiber optic cables for power, signaling, control, and communications. These cables have been designed and customized by a team of technicians to meet the standards of fire-resistant cables, which do not cause fire to spread in the event of a fire and greatly reduce the production of harmful and toxic gases.
All the above cable products can be used in many industrial projects, and customization of colors and packaging is available, in addition to a wide range of large mechanical equipment and cable accessories related to underground mining operations.
