Outside insulating protective layer, minor diameter is enclosed within OPGW terminal and reserves cable and be not provided with outside the part of insulating protective layer.So can
Make whole OPGW terminal reserve cable to be protected from.
It is to carry out joining dish by the route length of engineering design that site operation installs the order length of OPGW cable whole dish cable.It is congested with
Before the end cable of insulating jacket layer, 3～5 meters are used to traction；Typically cut when continuing, prevent from causing in traction impaired or
Disconnected bar affects engineering construction quality.
The sheath that blocks water should be enclosed within OPGW insulating jacket layer two ends, then enters with pyrocondensation equipment before the OPGW optical cable that continues
Row encapsulation；OPGW optical cable fibre core subsequent duty is carried out again completing to block water after sheath erector continues；Fibre core will connect after continuing
After continuous box cover locking, then carry out OPGW and reserve cable and be entangled in fork dish, and carry out reserved cable fastening work.
Additionally providing a kind of transformer station OPGW terminal and reserve the manufacture method of cable, it comprises the following steps:
(1) extruded on production line what Special end product cable gone up again by the OPGW finished product cable produced, carry out squeezing and apply absolutely
Edge protective jacket；
(2) two ends of the insulating sheath reserving cable in OPGW terminal are smeared waterproof gluing thing or are wound around insulating tape；
(3) protective jacket that blocks water is inserted in the position of insulating sheath and waterproof thing；
(4) by pyrocondensation processing equipment, the protective jacket that blocks water is carried out pyrocondensation process, prevent the OPGW light of having insulation sheath layer
The two ends of cable are opened, and eliminate the air in protective jacket that blocks water.
Preferably, according to electric pressure and the setting height(from bottom) of transmission tower, determine that OPGW terminal reserves cable 1 and tape insulation protects
The length of the OPGW optical cable 6 of jacket layer.
Preferably, in described step (2), the initiating terminal of insulating protective layer is located at OPGW terminal and reserves the tail end 2 of cable～5 meters
Place, the length of insulating protective layer is to require to manufacture according to user.
Preferably, the protective jacket 4 that blocks water described in described step (4) includes major diameter portion 41 and minor diameter 42, major diameter
Portion is enclosed within outside insulating protective layer, and minor diameter is enclosed within OPGW terminal and reserves cable and be not provided with outside the part of insulating protective layer.
The beneficial effects of the utility model are:
1) this utility model 100% solves extra-high voltage, supertension, high voltage substation OPGW terminal are wound around in reserving dish
The turn-to-turn contact discharge galvanic corrosion strand broking that OPGW turn-to-turn faradism causes.
2) this utility model method is that OPGW terminal is reserved cable before being entangled to reserved cable fork dish, uses insulant and fills out
Fill thing OPGW to be reserved after cable outer layer carries out all insulation PROCESS FOR TREATMENT and to be entangled to again in reserved cable fork dish, permissible after insulating process
100% ensures that OPGW reserves cable and turn-to-turn galvanic corrosion strand broking does not occur in fork dish.
3) cable turn-to-turn insulation technique is reserved in particular for ultra-high voltage transformer station OPGW terminal.
4) draw lower OPGW from shaft tower when continuing in particular for OPGW cable in the middle of OPGW cable insulated circuit and reserve the turn-to-turn of cable
Insulating process.
5) this utility model may be used in the reserved cable fork dish of multiple material, especially with metallic tines dish, does not occurs
Turn-to-turn cable strand broking.Owing to nonmetal fork cable dish production cost is higher, use band steel fork dish can reduce fork dish cost.
The above, be only preferred embodiment of the present utility model, and this utility model is not made any pro forma limit
System, every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model,
