产品详情资料
.砂、粗骨料和水泥应按设计配比
设计部门批准的混合料。预拌材料的测量
混凝土应符合预拌混凝土规范ASTM C 94
每立方米混凝土的小水泥含量不得小于250kg。
混凝土的成分应均匀，并在整个混合过程中保持一致
一批浇筑时的混凝土温度不得超过38°C
温和天气低于2°C。
f、 如果使用模板，这些模板应足够紧密，以防止砂浆损失
混凝土，并应严格保持到位，直到混凝土足够硬化
以防止因拆卸而损坏。
g、 如果基坑未开挖，承包商应仅支付SEC批准的基础尺寸
随着螺旋钻和更多土壤受到扰动，额外消耗的混凝土应负责
承包商。
h、 如果SEC工程师要求，则对电杆和锚的混凝土基础样品进行测试
应执行。七天后将混凝土样本压碎。
10.7导线
10.7.1中压导线
两种标准尺寸的ACSR/AW裸铝导线，符合SEC
规范10-SDMS-01用于架空一次配电系统，如下所示：
a、 梅林
Merlin ACSR/AW导线170.45 mm²（336.4 MCM），额定电流361安培。
断裂强度=38.22 kN
大设计载荷=9.55 kN。. The sand, coarse aggregate and cement shall be proportioned according to the design
mix approved by the design department. The measurement of material for ready mix
concrete shall conform to specification for ready mix concrete ASTM C 94. The
minimum cement content per cubic meter of concrete shall not be less than 250kg.

The concrete shall be uniform in composition and consistent through out the mixed
batch. Concrete temperature when being placed shall be not more than 38 °C and not
less than 2 °C in moderate weather.
f. Where forms to be used, these shall be sufficiently tight to prevent loss of mortar from
concrete and shall be maintained rigidly in position until concrete has hardened enough
to prevent damage by the removal.
g. The contractor shall be paid only for SEC approved foundation size, if the pit not dug
with auger and more soil disturbed, extra consumed concrete shall be the responsibility
of the contractor.
h. If required by SEC Engineer, the concrete foundation sample test of pole and anchor
shall be carried out. The concrete sample to be crushed after seven days.
