Overview

MYPTJ mining rubber sheathed wire MYP MY various voltage $r $n wire surface markings - According to national standards, the wire surface should have continuous markings of the manufacturer's name, product model, and rated voltage. This is beneficial for timely finding the manufacturer when problems occur during the use of wires, and consumers must pay attention to this when choosing wires. At the same time, consumers should pay attention to whether the manufacturer name, product model, rated voltage indicated on the certificate of conformity are consistent with the printed markings on the surface of the wire when purchasing wires, in order to prevent counterfeit products

The selection of cable models is closely related to the reliability, safety, and economic feasibility of power supply. 《Coal Mine Safety Regulations》Article 467 stipulates the following selection requirements for the selection of cables:

The level difference of the actual cable laying location should be compatible with the allowable cable laying level difference specified.

2. The cable should have a conductor of sufficient cross-section for protective grounding.

3. It is strictly prohibited to use aluminum wrapped cables.

4. Flame retardant cables that have passed inspection and obtained the safety mark for coal mining products must be selected.

5. The cross-section of the main cable core should meet the requirements of the power supply line load.

6. Requirements for fixed installation of high-voltage cables:

(1) In vertical shafts or tunnels with an inclination angle of 45 ° or more, the use ofpolyvinyl chlorideInsulated thick steel wire armored PVC sheathed power cablecross-linked polyethyleneInsulated thick steel wire armored PVC sheathed power cable.

(2) In horizontal tunnels or shafts with an inclination angle of less than 45 °, PVC insulated steel strips or fine steel wire armored PVC sheathed power cables, cross-linked ethylene steel strips or fine steel wire armored PVC sheathed power cables should be used.

(3) Aluminum core cables can be used in the air intake inclined shaft, underground parking lot and its vicinity, and between the central substation and the mining area substation; Copper core cables must be used in other locations.

(4) Fixed low-voltage cables should use Mw armored or unarmored cables or corresponding voltage level mobile cablesRubber sheathed flexible cable.

(5) Non fixed high and low voltage cables must use those that comply with the Mr818 standardRubber sheathed flexible cableMobile and handheld electrical equipment should use specialized equipmentrubber-sheathed cable.

(6) Cables used for lighting, communication, signaling, and control should be armored communication cables, rubber sheathed cables, or M, factory, factory type plastic cables.

(7) Aluminum cores should not be used for low-voltage cables, and aluminum cores are strictly prohibited for low-voltage cables in mining areas.

National Mining Product Safety Mark Center for Safety StandardsAccording to the Office of Safety Signs for Mining ProductsState Administration of Work SafetyAuthorize and undertake the management of safety signs for mining products, including accepting safety sign applications, organizing and implementing technical reviews, on-site evaluations, product sampling inspections, issuing safety signs, and supervising and managing enterprise certification. The National Mining Product Safety Mark Center adheres to the work policy of "fairness, openness, scientific efficiency, rigorous confidentiality, integrity and enthusiasm", strictly implements national laws and regulations and relevant provisions on safety production, operates in a procedural manner, and manages in a standardized manner. There are currently offices (Policy Research Office), Comprehensive Department (International Department, Information Department), Technical Department, Review Department, Inspection Department, Supervision Department, Finance Department and other departments.
