架空绝缘导线金具
Overhead Insulated Wire Fittings

JLC 系列 C 型线夹

JLC Series C Type Clamps

概述 /Outline
C 型线夹是导线接续型电力连接金具，主要用在架空绝缘导线、钢芯铝绞线、铝绞线、钢绞线和铜导线非承 C
力位置上 T 接续或跳线用。该线夹采用导电性能良好的高强度特殊铝合金制造，结构采用合理的 C 型和铰
型楔块构成，当铰型楔块在外力作用下，将导线压紧在线夹壳体和模块之间。当导线热胀冷缩时，C 型结构
应具有的弹性，始终保持线夹与导线间持久而恒定的接触压力。随着外界环境及负载条件的变化，而接触压 架空绝缘导线金具
力不变，满足了接续连接的最佳要求。
The C line clip is wire connection type electric connection fittings, mainly used in overhead insulated
wire, steel core aluminum strand, aluminum wire, steel wire and copper wire non load-bearing position
T connection or jumper with. The line clamp is made of conductive good performance of high strength
aluminum alloy manufacturing structure by reasonable type C and type hinge wedge blocks, when type
hinge wedge under the external force, the wire pressing clamp casing and between modules. When
thermal expansion and contraction of the wire and C type structure should have the flexibility, and always
maintain the clamp and the wires between the lasting and constant contact pressure. With the change of
the external environment and the load condition, the contact pressure is invariable, which satisfies the best
request of the connection.

铜铝过渡板 ( 闪光焊 \ 摩擦焊 )
Copper to aluminium adapter board (Flash welding / friction welding) ◆ Contact performance: clamp and wire contact surface, the clamping force is constant, the rate of DC
resistance in 0.85~0.9.
◆ Overload capacity: overload ability to achieve the approved current more than 2 times;
◆ Firm performance: high strength material, stainless steel bolt fastening, the connection is reliable;
◆ Thermal cycling performance: the thermal cycling performance is good, always in the DC resistance
ratio of 1 the following operation;
◆ Installation: installation and removal is convenient, suitable for aerial work;
◆ Energy saving performance: the material uses the high strength special aluminum alloy manufacture,
does not have the electromagnetic loss.
Small contact resistance and good thermal cycling performance, strong overload capacity, energy saving,
. convenient installation, maintenance free, zero fault. Long-life and excellent quality. In the selection, whether it is
the transmission line, but also the distribution line only 1 connection can be used.
