without any scratch, rust, crusting and cracks.
6) The labels are clear and complete.
Insulation resistance: under normal ambient conditions, after high
temperature test, low temperature test, temperature varing test and
humidity heat test, the insulation resistance between any two
independent contacts, and/or between contacts and metal parts ≥
1000MΩ
Contact resistance between contacts: under normal ambient
conditions, the contact resistance between contacts ≤7 mΩ. After
high temperature test, low temperature test, temperature varing
test and humidity heat test, the increasing resistance ≤3 mΩ And
after inserting the connection cord (or test cord) into the module
for 200 times, the increasing resistance ≤3 mΩ
Contact resistance between conductor and contact: under normal
ambient conditions, the contact resistance between contacts ≤3 mΩ.
After high temperature test, low temperature test, temperature
varing test and humidity heat test, the increasing resistance ≤2
mΩ. And after terminating for 200 times, the increasing resistance
≤2 mΩ.
Dielectric strength: under normal ambient conditions, after high
temperature test, low temperature test, temperature varing test and
humidity heat test, the insulation resistance between any two
independent contacts, and/or between contacts and metal parts is
able to withstand an AC voltage of of 1000V (virtual value) at
45Hz~60Hz sinowave for 1 minute, without spark over and flying arc
Gas tight performance: contact touches the conductor at both sides,
and thus forming the gas tight area, while the area of gas tight
occupies ≥50% of the touched area on each side.
Conductor diameter range: 0.32mm-0.6mm, while insulation ≤ 1.4mm
Pulling strength:≥25N while pulling from the vertical side of the
contacts
Flame retardant performance: all plastic parts are flame retardant,
reaching grade of UL FV0
Life circle: ≥200 times
Outdoor DP Box Plastic for STB Modules 20pairs
Empty distribution box for 1pair dropwire module(STB
module),offerring good connection environment for
telecommunication.
Material:PC,with steel rails.
The subscriber connector unit consists of a rectangular box base
with a cover and a connection module secured to the base.The top
and base are hinged together, and the top is easily removable to
facilitate working in cramped conditions.The cable grommets for
wire entry and exit may be adjusted to conductor size and are also
removable.A metal screw is provided for grounding purposes.
Application for replacing Tyco VX-SB subscribe connector unit
terminal blocks,Connecting 1 pair module without protection,module
with surge protection (gas-discharge instrument with surge
protection to 230V) and module with overvoltage and overcurrent
(overvoltage to 230V, and by two resistors PTC, which protect from
the overcurrent).
