FHG6 Mine fiber junction box Product Name: Mine fiber junction box Specifications Model: FHG6 standards and requirements: GB3836.1-2010, MT / T1033-2007, Q / LY1010.8-2014 Scope: in strict accordance with the relevant provisions of mine safety use. Keywords: Specifications FHG4 Stone, six-way, etc. (six-way or four-way A6 B6 or customized according to customer requirements) Name: Mine fiber optic terminal box Technical parameters: 12 cores, 24 cores, 36 cores, 48 ??cores. Scope: coal mine gas and coal dust in the environment, as the fiber optic cable connection. Wiring Uses: This product can only be used at the mine fiber optic cable connection. Ordering Information: when ordering the number of orders, specifications and connected with the cable diameter. Note: Due to the fiber is not charged, so from last year, with a fiber optic terminal box mine coal safety certificate issued only, do not send proof card. Please ask the national security standard testing center center or across the country. JHHG mine design intrinsically safe fiber optic cable tray down box is open type, opening the housing just unscrew the four fixing screws for easy and reliable installation. Housing made of high quality ABS plastic, looks nice. Fiber discs are housed inside the box flip design, the opening angle of up to 90 ° or more, fixed heat shrink tubing, coiled fiber, expansion, and maintenance are very convenient. Explosion-proof type: Mine intrinsically safe explosion-proof mark: ExibI; FHG4 mineral fiber distribution box / JHHG mine fiber optic cable tray box 1.FHG4 Stone, FHG6 Liutong Subject Matter and Scope This standard specifies the FHJG4 mineral fiber junction box (hereinafter referred to as junction boxes) the type and basic parameters, requirements, test methods, inspection rules and signs, packaging, transportation, storage and so on. This standard applies to mineral fiber junction box, which is mainly used in coal mine junction box to connect fiber optic cables transmit signals to continue transmitting optical signals. 2.FHG4 Stone, FHG6 referenced standard six-way packaging Pictorial marking GB191 GB 3836.1-2000 environment proof electrical equipment General requirements GB 3836.4-2000 environment proof electrical equipment Intrinsic safety "i" GB 4208 enclosure protection (IP code) GB 1410 solid electrical insulation, resistance volume resistivity and surface resistivity test method GB 4208-1993 Protection IP code GB / T 10111 using a random number of dice random sampling method GB / T 12173 Mine general electrical equipment GB / T 13993.2 communications cable series Part 2: Outdoor optical fiber core network MT209 mine communications, detection, control electrical and electronic products general technical requirements MT210 mine communications, detection, control electric and electronic products - Test methods MT286 mine communication, automation Model methodology and management methods YD / T 629.1 fiber transmission attenuation change detection method for transferring power monitoring method YD / T 814.1 cable connector box Part 1 outdoor cable connector box YD / T 1024 light fixed joint protection organization before MT / T 1033-2007 mine fiber access, junction box after box test points drop hit by a non-working state, the appearance shall comply with the provisions of Article 4.4 of this standard, the performance should be consistent with the provisions of this standard 4.7.
